how many nuclear warheads are on a trident missile?

An extensive upgrade for 300 missiles is planned in 2020 in order to upgrade them to the Trident D-5A or D-5LE versions with improved capabilities and an extended service life to 2042.3, In the mid-2000s, the Defense Department requested to deploy conventionally-armed Trident D5 missiles to satisfy requirements for its Conventional Prompt Global Strike capability. Each Trident missile can carryup to eightnuclear warheads, but usually carry four to five for an average of 90 warheads per submarine. Two B-52s, in two hours, can monitor 140,000 square miles (364,000 square kilometers) of ocean surface. It relies on an existing US. The Trident warheads are launched by three solid-fueled booster stages and are dispersed toward their targets by a liquid-fueled bus in the missiles front end. Each submarine can carry 16 missiles and are equipped with UK warheads believed to be similar to the W76 100 kT US warheads. The fire control system was designed and continues to be maintained by General Dynamics Mission Systems. Each nuclear-powered Columbia-class submarine will carry up to 16 Trident D-5 submarine-launched ballistic missiles (SLBMs). The missile measures 13.42 m in length, 2.11 m in diameter, and weighs 59,090 kg at launch. The United Kingdom maintains a fleet of four ballistic missile submarines with the ability to devastate even the largest of countries. The Air Force would like toreplace the Minuteman IIIs with the Ground-Based Strategic Deterrent (GBSD). The combat effectiveness of the B-2 was proved in Operation Allied Force, where it was responsible for destroying 33 percent of all Serbian targets in the first eight weeks, by flying nonstop to Kosovo from its home base in Missouri and back. 2023 Center for Strategic and International Studies. The Navy says. In the United States' current nuclear arsenal, the most powerful bomb is the B83, which has a maximum yield of 1.2 megatons, making it 60. Guidance System: Inertial. US Navy Vice Admiral Johnny Wolfe, in charge of overall submarine weapons systems procurement, indicated in 2020 that he had initiated trade studies to apply lessons from the D5LE program to extend the Trident II's lifespan to 2084. The C4 and D5 designations put the missiles within the "family" that started in 1960 with Polaris (A1, A2 and A3) and continued with the 1971 Poseidon (C3). The ugm133a trident ii or trident d5 is a submarine-launched ballistic missile that is a critical component of the United States' strategic nuclear triad. Ballistic missile submarines are specifically designed for extended deterrent patrols. On average, the submarines spend 77 days at sea followed by 35 days in port for maintenance. Most modern design support Multiple Independently targetable Re-entry Vehicles (MIRVs). B-52s struck wide-area troop concentrations, fixed installations and bunkers, and decimated the morale of Iraq's Republican Guard. The United States is in the process of modernizing its nuclear-capable aircraft with the F-35 and B-21 Raider. However, these are intended primarily for self-defensea ballistic missile submarines job isnt to hunt enemy ships and submarines, but to lie as low and quiet as possible to deny adversaries any means of tracking their movements. It could deliver eight independently targetable 100-kiloton nuclear warheads to a range of 4,000 nautical miles (7,400 km). The U.S. Navy has deployed a new type of "low-yield" nuclear warhead in some of its Trident submarines . The Trident was built in two variants: the I (C4) UGM-96A and II (D5) UGM-133A; however, these two missiles have little in common. Of the eight submarines, five are usually out at sea when they are not receiving maintenance at Bangor . BrahMos The Trident II, or D-5, is about 46 feet (14 metres) long and carries multiple independently targeted warheads. The UGM-133 Trident II D5 is a three-stage, solid-fueledsubmarine-launched intercontinental-range ballistic missile. The pods advanced targeting and image processing technology significantly increases the combat effectiveness of the B-52 during day, night and under-the-weather conditions in the attack of ground targets with a variety of standoff weapons (i.e., laser-guided bombs, conventional bombs and GPS-guided weapons).

On September 17, the U.S. Navy launched two unarmed Trident II D5 Life Extended (LE) submarine-launched ballistic missiles (SLBM) in a scheduled flight test in waters off Cape Canaveral, Florida. GPS has been used on some test flights but is assumed not to be available for a real mission. A compilation of platforms and weapons, the three legs of the U.S. nuclear triad serve as the backbone of Americas national security. In a conventional conflict, the B-52 can perform strategic attack, close-air support, air interdiction, offensive counter-air and maritime operations. Depot maintenance responsibility for the B-2 is performed by Air Force contractor support and is managed at the Oklahoma City Air Logistics Center at Tinker Air Force Base, Oklahoma. The Guidance System for the missile was developed by the Charles Stark Draper Laboratory and is maintained by a joint Draper/General Dynamics Mission Systems facility. The energy from the blast is directed to a water tank, where the water is flash-vaporized to steam. Each warhead has approx 400kt of explosive yield (explosive power equivalent to 400,000 tonnes of TNT). The Royal Navy will builds four Dreadnought-class subs, each weighing 17,200 tons, with construction beginning in September 2016. 2 How many missiles does a Trident submarine carry? Originally developed by Lockheed Missiles and Space Corporation, the missile is armed with thermonuclear warheads and is launched from nuclear-powered ballistic missile submarines (SSBNs). Ohio-class submarines also come armed with four twenty-one-inch tubes that can launch Mark 48 torpedoes. Our editors will review what youve submitted and determine whether to revise the article. What is the most dangerous missile in the world? Complicate enemy attack & capable of providing prompt, overwhelming response. The introduction of the third generation Dreadnought class will provide the UK with a powerful strategic deterrent until the 2060s and possibly beyond. Each will have twelve missile tubes instead of sixteen, and the subs will recycle the Trident II D-5 missiles from their predecessors. The five-decade-old Minuteman III will be replaced by the $100 billion. Although each submarine has sixteen launch tubes, a decision was made in 2010 to load each sub with just eight American-built Trident II D-5 submarine launched ballistic missiles. How many missiles does a Trident submarine carry? It is designed to be launched from submarine ballistic missile tubes. The prime contractor, responsible for overall system design and integration, is Northrop Grumman Integrated Systems Sector.

However, Congress rejected funding for this program.4, In June 2002, the Navy initiated the D5 Life Extension to replace aging missile parts and extend missile life from 30 to 44 years.5, In January 2021, VADM Johnny Wolfe announced the Navy would start the Trident D5 Extension Life II upgrade this year.6 The second life extension program seeks to increase the Trident D5s lifespan for another 60 years to deploy through the 1980s.7, Since the Tridents design completion in 1989, the U.S. Navy has successfully conducted over 160 missile test launches.8, The Trident D5 has a range of 12,000 km and can carry a payload as large as 2,800 kg. ", "Today, we face a complex and volatile global security environment with a wide range of challenges. At least thats the hope. It is three-staged and uses solid-propellant.9, The 2018 Nuclear Posture Review highlighted the need for a new low-yield Trident missile to deter adversary use of similarly low-yield nuclear weapons.10 Congress appropriated $65 million in FY2019 and $10 million in FY2020 to fund the new warhead, which was designated the W76-2. Corrections? A Trident submarine off the coast of Southern California in 2004. It has a maximum range of about 6,500 nautical miles (12,000 km). Point of Contact How many nuclear warheads can a Trident missile carry? The Trident II is a long-lasting c-based device capable of attacking a wide range of targets. Current engineering analyses show the B-52's life span to extend beyond the year 2040. It improved upon earlier SLBMs including the Polaris, Poseidon, and Trident I C4. We use cookies to ensure that we give you the best experience on our website. The Ohio-class design allows the submarines to operate for 15 or more years between major overhauls. Under development from the late 1960s, the Trident developed into two models. At any one time, at least sixty-four of the UKs nuclear weapons are somewhere at sea, ready to launch within minutes of warning. Today's Minuteman weapon system is the product of almost 60 years of continuous enhancement. Trident missiles have can range up to 7,500 miles, and the destructive force is equivalent to eight Hiroshimas. How many nuclear warheads can a Trident missile carry? A 1999 UK statement limited the number of warheads to be deployed on each submarine to 48, an average of 3 warheads per missile.14 In July 2016, Parliament voted to approve new SSBNs to preserve the UK nuclear deterrent, ensuring that Trident will be deployed into 2050s.15. The primary drawback of using conventionally armed ballistic missiles is being virtually indistinguishable by radar warning systems from nuclear armed missiles. 1 How many warheads are on a Trident missile? While a submarines missiles are not pretargeted, like those in in fixed silos, they can be assigned coordinates quite rapidly. Between 1994 and 1999 the United Kingdom commissioned its Vanguard submarines to carry the Trident II, which was fitted with warheads of British design. Resolution first successfully launched a missile off the coast of Florida in February 1968. US Navy test firing two Trident II D-5 UGM-133A missiles in the Atlantic Missile Range, June 2014 (DASO 25 SSBN 736) during a Demonstration and Shakedown Operation. Nuclear warhead limit: Seven years after entry into force (Feb. 5, 2018), New START limits went into effect that capped accountable deployed strategic nuclear warheads and bombs at 1,550, down approximately 30 percent from the 2,200 limit set by SORT and down 74 percent from the START-accountable limit of 6,000. Each Trident missile can carry 8 Multiple Independent Reentry Vehicles (MIRV's) armed with a nuclear warhead. Contractor: Northrop Grumman Corp. and Contractor Team: Power Plant: Four General Electric F118-GE-100 engines, Maximum takeoff weight: 336,500 pounds / 152,634 kilograms, Fuel Capacity: 167,000 pounds / 75,750 kilograms, Payload: 40,000 pounds / 18,144 kilogramst, Armament: Conventional or nuclear weapons, Unit Cost: Approximately $1.157 billion / fiscal 1998 constant dollars, Inventory: Active Force - 21 (1 test) | Reserve - 0 | Air National Guard - 0. The B-52 also played a role in Operation Iraqi Freedom. Less than a month later, the United States would become the only nation to use nuclear weapons in a conflict, dropping atomic bombs onHiroshima and Nagasaki. All 24 missiles can be launched in less than one minute. Yields are probably 0.3 kt, 5-10 kt and 100 kt. Each Trident carries between one and 14 warheads. The first submarine, HMS Resolution, was laid down in 1964 and commissioned in 1967, followed by Repulse and Renown, commissioned in 1968, and the aptly-named Revenge in 1969. There may be an additional need to conduct end-to-end tests of Trident D5s that reflect the introduction of the new W76-2 low-yield warhead for those missiles, the last examples of which were . This is a. The U.S. Navy has 14 Ohio-class ballistic missile submarines, eight of which operate out of Bangor, Washington, and six of which operate out of Kings Bay, Georgia. The Ohio-class boats entered service in the 1980s as a replacement for five different classes of fleet ballistic-missile submarines, collectively known as the 41 for Freedom. Displacing more than eighteen thousand tons submerged, the new boomers remain the largest submarines to serve in the U.S. Navyand the third largest ever built. Each Trident missile can carry up to eight nuclear warheads, but usually carry four to five for an average of 90 warheads per submarine. There are eight Trident submarines that hold 20 D5 missiles per sub. The B-52 is slated to be in service beyond 2040. However, rather than retiring some of the oldest boats as originally planned, the Navy decided to refit four of the eighteen Ohio-class subs to serve as cruise missile carriers to launch conventional attacks against ground and sea targetsstarting with theUSS Ohio. Omissions? Trident missiles are deployed in four submarines, one of which is continuously at sea to make sure it can strike back in the event of an unprovoked nuclear attack. . It is highly effective when used for ocean surveillance, and can assist the U.S. Navy in anti-ship and mine-laying operations. The B-52 is a long-range, heavy bomber that can perform a variety of missions. [13] This requires a D5 Life Extension Program (D5LEP), which is currently underway. A small number of W76-2 low-yield warheads have also been deployed on some Ohio-class submarines. More than half of deployed US strategic warheads are mounted on submarine-launched missiles, and the remainder are nuclear bombs and warheads on air-launched cruise missiles in storage bunkers at the three US strategic bomber bases. Several methods have been developed to carry out this task. The end of the Cold War, and especially the Strategic Arms Reduction Treaty, resulted in the downsizing of U.S. nuclear forces. How much damage would a Trident missile do? 820 1st Street NE, Suite LL-180 Through various arms control agreements and unilateral reductions, the United States has atotal inventory of around 5,550nuclear warheads. The Bulletin of the Atomic Scientists says the Russian arsenal includes 4,447 warheads, of which 1,588 are deployed on ballistic missiles and at heavy bomber bases. Trident is Britain's nuclear weapons system. USS Henry M. Jackson (SSBN 730), Bangor, Wash. USS Pennsylvania (SSBN 735), Bangor, Wash. USS West Virginia (SSBN 736), Kings Bay, Ga. USS Rhode Island (SSBN 740), Kings Bay, Ga. For more than six decades, the United States has emphasized the need for a nuclear force that credibly deters adversaries, assures allies and partners, achieves U.S. objectives should deterrence fail and hedges against uncertain threats. Americas bomber fleet provides a range of both conventional and nuclear response options. This number would later be reduced to four submarines. Sagarika has . Strategic Systems Programs They haven't been detonated in war since then. Both the missile and basing components incorporated significant advances beyond the relatively slow-reacting, liquid-fueled, remotely controlled intercontinental ballistic missiles of the previous generation. The ministry expects the new submarines to cost an estimated $39 billion over thirty-five years, with a $12 billion contingency. The B-2's low observability is derived from a combination of reduced infrared, acoustic, electromagnetic and visual and radar signatures. Feb 18, 20206:02 PM. The Trident missile was first developed in the late 1960s by the United Kingdom, United States, and Canada as a successor to the Polaris missile. In 2009, the United States upgraded the D5 missiles with an arming, fuzing and firing (AF&F) system called the "super-fuze"[7][8] that allows them to target hardened silos and bunkers more accurately. The United Kingdom is estimated to possess 225 nuclear weapons, of which 120 are operationally available and only 40 are deployed at a time. Warren Air Force Base, Wyoming; the 341st Missile Wing at Malmstrom Air Force Base, Montana; and the 91st Missile Wing at Minot Air Force Base, North Dakota. They are designed specifically for stealth and the precise delivery of nuclear warheads. Pilots wear night vision goggles, or NVG, to enhance their vision during night operations. The first aircraft, Spirit of Missouri, was delivered Dec. 17, 1993. The UK Navys forthcoming Dreadnought-class submarine will equip the Trident D5 as it enters service in the early 2030s. This mixture is sent up into the air and then falls back to Earth. The UK has been estimated to have around 120 active nuclear warheads, with 215 warheads in its arsenal in total. Night vision goggles provide greater safety during night operations by increasing the pilot's ability to visually clear terrain, to increase the peacetime and combat situational awareness of the aircrew and visually acquire other aircraft. The warheads are either the 90-kiloton W76-1 or the 455-kiloton W88. In 1971, the US Navy began studies of an advanced Undersea Long-range Missile System (ULMS). The Navy's ballistic missile submarines, often referred to as boomers, serve as an undetectable launch platform for missiles. A Decision Coordinating Paper (DCP) for the ULMS was approved on 14 September 1971. The name of Britain's nuclear weapons program is Trident, and the country has had nuclear weapons since the 1950s. The UK has approximately 225 nuclear weapons, and initiated its nuclear arms programme during the Second World War. Copyright 2023 Center for the National Interest All Rights Reserved, Polaris A-3 submarine-launched ballistic missiles. The warheads are though to have similar characteristics to the U.S. W-76 now on U.S. Trident I and II missiles. A midlife improvement for the missile, Polaris A-3TK, replaced the single warhead with two Chevaline warheads plus penetration aids. Its unrefueled range is approximately 6,000 nautical miles (9,600 kilometers). The country with the third most nuclear warheads is China with 350. The increased limit, from 180 to 260 warheads, is contained in a leaked copy of the integrated review of defence and foreign policy, seen by the Guardian. The Royal Navys ballistic missile submarines carry on the services centuries-old mission of protecting the country from the sea. Under a program known as Continuous At Sea Deterrence (CASD) at least one submarine is on patrol at all times, with another coming off patrol, another preparing for a patrol and a fourth undergoing maintenance. You can follow him on Twitter: @KyleMizokami. As such, the Trident-armed Ohio-class submarines will have succeeded in their mission if they never fire their weapons in anger. The Royal Navy's nuclear submarine - HMS Vanguard - is 150 metres long. The main aim is to replace obsolete components at minimal cost[citation needed] by using commercial off the shelf (COTS) hardware; all the while maintaining the demonstrated performance of the existing Trident II missiles. These RVs can beeither the Mk 4 with a W76 100 kT yield warhead or the Mk 5, which has a W88 475 kT yield warhead. More than 10,000 people provide up to 400 on-alert, combat-ready LGM-30G Minuteman III intercontinental ballistic missiles, or ICBMs, in hardened silos across five states. Should command capability be lost between the launch control center and remote missile launch facilities, specially configured E-6B airborne launch control center aircraft automatically assume command and control of the isolated missile or missiles. Modern nuclear warheads are far more powerful with the U.S. Trident missile yielding a 455 kiloton warhead while Russia's SS ICBM has an 800 kiloton yield. Ohio-class/Trident ballistic missile submarines provide the sea-based leg of the triad of U.S. strategic offensive forces. The Trident D5 entered service in 1990.1, The Trident D5 was originally intended to significantly increase range compared to the first-generation Trident I C4. In support of Operation Enduring Freedom, the B-2 flew one of its longest missions to date from Whiteman to Afghanistan and back. The Trident missile is a submarine-launched ballistic missile (SLBM) equipped with multiple independently targetable reentry vehicles (MIRV). Trident missiles are provided to the United Kingdom under the terms of the 1963 Polaris Sales Agreement which was modified in 1982 for Trident. The Trident missile rises into space above missile defense systems and releases the MIRVs. Should the missile fail to breach the surface of the water, there are several safety mechanisms that can either deactivate the missile before launch or guide the missile through an additional phase of launch. Copyright 2023 Center for the National Interest All Rights Reserved, receive some additional acoustic stealth upgrades. The UK again decided to build its own submarines and outfit them with American missiles. Fourteen Ohio-class SSBNs make up the most survivable leg of the nuclear triad. It's key to our nation's defense. With inertial guidance refined by stellar or satellite navigation, Tridents are more accurate than most land-based ballistic missiles. Whiteman Air Force Base, Missouri, is the only operational base for the B-2. Each Trident missile can carry 8 Multiple Independent Reentry Vehicles (MIRVs) armed with a nuclear warhead. Let us know if you have suggestions to improve this article (requires login). Hard to take out. The Trident II was the original missile on the British Vanguard-class and American Ohio-class SSBNs from Tennessee on. In less than a decades time, there would be dozens ofrealundersea beasts capable of destroyingmultiplecities at a time. Phone: 202.546.0795, 2023 Center for Arms Control and Non-Proliferation The Trident D-5 is a solid rocket fuel missile with a range of 4,600 miles, and it's capable of carrying up to 14 W-76-1 thermonuclear warheads, each with a destructive power six times greater . Occasionally, these chaps will spawn into the world holding a trident, so you simply have to defeat them for a chance of a trident dropping, but that chance is very small at 8.5%. 3 What is the most dangerous missile in the world? On March 21, 2003, B-52Hs launched approximately 100 CALCMs during a night mission. For that reason among others, this project raised a substantial debate before US Congress for the FY07 Defense budget, but also internationally. How many nuclear warheads does the UK have? The missiles, missile launch tubes and fire control mechanisms, however, were built in the United States. Skybolts cancellation threatened to undo the UKs entire nuclear deterrent, and the two countries raced to come up with a solution. While other branches of the military may be deployed in reaction to the crisis of the day, the nuclear submarines maintain a steady routine of patrols, and communicate infrequently so as to remain as stealthy as possible. [18][19]. The submarines nuclear reactor gives it virtually unlimited underwater endurance and the ability to maintain cruising speeds of twenty knots (twenty-three miles per hour) while producing very little noise. Our interactive tool visualizes every bomb and warhead in the US nuclear arsenal. Only the H model is still in the Air Force inventory. The W93 would be the first new nuclear warhead design for America's military since the 1980s. A total of 744 B-52s were built with the last, a B-52H, delivered in October 1962. The proposed program would cost more than $100 billion and consist of 666 missiles 400 for deployment and 266 for test launches or as spares. The UGM-133 Trident II D5 is a three-stage, solid-fueled submarine-launched intercontinental-range ballistic missile. The Ohio submarines were built with larger missile tubes designed to accommodate the newer Trident II beginning in 1990. Here are the 10 countries with the most submarines: R-36M (SS-18 Satan) This Russian Intercontinental ballistic missile is the heaviest and most powerful in the world. This maximizes the submarines strategic availability, reduces the number of submarines required to meet strategic requirements and allows for proper crew training, readiness and morale. The Minuteman III missiles underwent a multi-billion dollar modernizationprogram in 2015, extending the service life of these missiles to 2030. While nowhere near as powerful as the U.S. strategic deterrent,. Its payload carries a Post-Boost Vehicle (PBV) which can carry up to 12 Reentry Vehicles (RVs), though New START limits the number to eight. Range: 4,000 nautical miles (4,600 statute miles, or 7,360 km). Currently the UK has just under 200 warheads that were introduced in the 1990s under the codename. The Polaris had a range of 2,500 miles and was originally equipped with a single British warhead. If you continue to use this site we will assume that you are happy with it. An intercontinental ballistic missile (ICBM) is a ballistic missile with a range greater than 5,500 kilometres (3,400 mi), primarily designed for nuclear weapons delivery (delivering one or more thermonuclear warheads). The Trident missile rises into space above missile defense systems and releases the MIRV's. Trident missiles are carried by fourteen United States Navy Ohio . Land France mainly breaks with the UK on nuclear weapons in that they have 50 or so aircraft that can launch missiles with a range of about 300 miles that deliver nuclear warheads, according to Kristensen. Technologies Chemical Systems Division Thrust: First Stage: 203,158 pounds | Second Stage: 60,793 pounds | Third Stage: 35,086 pounds, "The nuclear strategic triad is the most important part of our military. The Columbia-class SSBN program will begin to replace the Ohio-class SSBNs starting in the early 2030s. If you do the math, the Ohio-class boats may be the most destructive weapon system created by humankind. Both Trident versions are three-stage, solid-propellant, inertially guided missiles, and both guidance systems use a star sighting to improve overall weapons system accuracy. An unarmed Trident II D5 missile launches from the Ohio-class ballistic missile submarine Rhode . The current ICBM force consists of Minuteman III missiles located at the 90th Missile Wing at F.E. With estimated costs of $46 billion each to manufacture, the next-generation boomers may be fewer in number and will use new reactors that do not require expensive overhauls and refueling, allowing them to serve on until 2085. [22] Russian President Vladimir Putin, among others, warned that the project would increase the danger of accidental nuclear war. All rights reserved. Minutes after launch, the missile is outside the atmosphere and on a sub-orbital trajectory. 5 How many Trident II missiles are on a Vanguard class submarine? . Kyle Mizokami is a defense and national-security writer based in San Francisco who has appeared in the Diplomat, Foreign Policy, War is Boring and the Daily Beast. While a submarines missiles are notpretargeted, like those in in fixed silos, they can be assigned coordinates quite rapidly. The use of aerial refueling gives the B-52 a range limited only by crew endurance. Each of these bombs is around eight times as destructive as the bomb which flattened Hiroshima in 1945, killing over 140,000 civilians. The launches mark On February 9, the U.S. Navy flight tested an unarmed Trident II submarine-launched ballistic missile (SLBM) from waters off the Florida coast. It is the sole strategic-range nuclear weapon of the United Kingdom and constitutes the sea-based leg of the United States nuclear forces. It paves the way for a controversial. In 2007, a B-52 Stratofortress took off from Minot mistakenly loaded with six nuclear-armed AGM-129 cruise missiles and flew across the country to Barksdale Air Force Base in Louisiana. How to Market Your Business with Webinars? Why is the Trident II used for nuclear deterrence? Beginning in 1979, Trident I missiles were fitted aboard older U.S. Poseidon-carrying submarines and newer Ohio-class vessels. Minuteman's maintenance concept capitalizes on high reliability and a "remove and replace" approach to achieve a near 100% alert rate. The Trident II D-5 has a range of 4,600 miles, meaning it can strike targets across European Russia with ease. The Trident II, or D-5, is about 46 feet (14 metres) long and carries multiple independently targeted warheads. The aerospike, a telescoping outward extension that halves aerodynamic drag, is then deployed, and the boost phase begins. Weight: 130,000 pounds (58,500 kg). Updates? In 2016, the Ministry of Defense announced the next generation of nuclear-powered ballistic missile submarines, dubbed Successor, would be the Dreadnought class. In US service Trident II can be loaded with up to eight Mk-5 RVs with 475-kt W88 warheads, up to fourteen Mk-4A RVs with 90-kt W76-1 warheads, and up to fourteen Mk-4A RVs with 57-kt W76-2 warheads. The missile is pressurized with nitrogen to prevent the intrusion of water into any internal spaces, which could damage the missile or add weight, destabilizing the missile.

how many nuclear warheads are on a trident missile? 2023
