  • Here’s how many nuclear warheads exist, and which countries own them

    Here’s how many nuclear warheads exist, and which countries own them

    By: Kelsey Reichmann WASHINGTON — The number of warheads has decreased over the past year, even as countries continue to modernize their nuclear forces, according to an annual assessment of global nuclear arms. The Stockholm International Peace Research Institute released the SIPRI Yearbook 2019 on the current state of armaments, disarmament and international security. The report found that 13,865 warheads in existence at the start of 2019 were owned by nine nations: the United States, Russia, the United Kingdom, France, China, India, Pakistan, Israel and North Korea. The year before hosted an arsenal of 14,465 warheads. “A key finding is that despite an overall decrease in the number of nuclear warheads in 2018, all nuclear weapon-possessing states continue to modernize their nuclear arsenals,” Jan Eliasson, SIPRI Governing Board chair ambassador and former deputy secretary-general of the United Nations, said in a news release. The U.S. and Russia were the only nations that decreased their warhead inventory, by 265 and 350 respectively, according to the report. The U.K., China, Pakistan, North Korea and possibly Israel all increased their number of warheads, SIPRI found. India and France saw no changes to the size of their arsenals. One big cause of the decrease in arsenal size, according to SIPRI, is the implementation of the New START Treaty between the U.S. and Russia, meant to reduce and set limits on ballistic missiles. The two nations produce more than 90 percent of the world's nuclear arms. The U.S. and Russia announced in 2018 that they had met the limits of the New START Treaty. But if an extension is not implemented, the treaty will expire in 2021. What's the United States up to? The U.S. is in the process of modernizing its nuclear arsenal per the Trump administration 2018 Nuclear Posture Review, which put forth measures to continue a modernization program started by the Obama administration. However, the NPR moves away from reducing nuclear weapons and instead sets a plan to develop new versions while and modifying others. The U.S. hopes to achieve its goals by expanding nuclear options to include low-yield nuclear weapons, which will expand capabilities associated with submarine-launched ballistic missiles. This would add to a U.S. arsenal that already contains 1,000 gravity bombs and air-launched cruise missiles with low-yield warhead options, according to the SIPRI report. The NPR claims these new capabilities are necessary without evidence that the existing arsenal is insufficient. The SIPRI report notes that America's focus on its nonstrategic nuclear arsenal could push other nations in that same direction. Where does Russia stand? “Russia's decisions about the size and composition of its non-strategic nuclear arsenal appear to be driven by the USA's superiority in conventional forces and not by the US non-strategic nuclear arsenal or by weapons yield," according to the SIPRI report. "Instead, pursuit of a new [submarine-launched cruise missile] to ‘provide a needed non-strategic regional presence' in Europe and Asia could — especially when combined with the parallel expansion of US long-range conventional strike capabilities — strengthen Russia's reliance on non-strategic nuclear weapons and potentially could even trigger Chinese interest in developing such a capability,” the report adds. SIPRI data shows Russia has about 4,330 nuclear warheads; approximately 1,830 of them are categorized as nonstrategic. In 2018, Russia continued long-range operations over the Arctic, Atlantic and Pacific oceans. And in December, it also sent to Venezuela two Tu-160 planes, which are part of its long-range aviation command fleet. Russia also fired air-launched cruise missiles from a Tu-160 bomber over northern Russia in November, which caught attention because the number of cruise missiles launched. Meanwhile, in China, India and Pakistan ... China has an estimated 290 nuclear warheads. Though China is working to expand its nuclear forces, the report notes, it has said it's committed to a no-first-use policy. However, the report added that China has taken steps to improve its retaliation response. Rivals India and Pakistan each provide little information about the size of their nuclear arsenals. However, they have made separate statements about missile tests. India has an estimated 130-140 warheads, and Pakistan has an estimated 150-160 warheads. Both nations are estimated to have increased their arsenal by 10 to 20 warheads in the last year. North Korea has provided little transparency about it nuclear weapons capabilities, besides announcing missile tests afterward. It's estimated the country has 20-30 warheads, which would be an increase of 10-20 warheads from a 2018 estimate. The SIPRI report cites a lack of transparency from most nations in regard to nuclear stockpiles. The U.S., the U.K. and France have disclosed some information about their respective arsenals. Information from other nations is mainly based on missile tests and the supply of military fissile materials. https://www.defensenews.com/global/2019/06/16/heres-how-many-nuclear-warheads-exist-and-which-countries-own-them/

  • Soldiers to evaluate new light tank prototypes

    Soldiers to evaluate new light tank prototypes

    Jen Judson WASHINGTON — The U.S. Army is preparing a soldier vehicle assessment of two different light tank prototypes for infantry brigade combat teams that will start in January 2021 at Fort Bragg, North Carolina. The assessment will run through June 2021, according to the service. BAE Systems and General Dynamics Land Systems were chosen in December 2018 to each build 12 prototypes of the Army's future mobile protected firepower, or MPF, vehicle identified in the service's ground combat vehicle strategy published in 2015. The service had found the capability one the service lacks. GDLS is building a vehicle that takes the United Kingdom's AJAX chassis and combines it with an M1 Abrams tank turret. BAE Systems' design is an updated M8 Buford armored gun system with new capabilities and components. “I just had my deep dive today on the SVA [soldier vehicle assessment] with the 82nd [Airborne],” Maj. Gen. Brian Cummings, the Army's program executive officer for ground combat systems, told Defense News in a recent interview. Work is ongoing to prepare ranges and roads for the arrival of the prototypes, he said. The MPF is going to be critical for the infantry because it provides infantry brigade combat teams with an organic capability to take care of impediments to forward progression such as gunfire from a machine gun nest or another enemy vehicle. The Army is expected to choose a winner in 2022. The first units will get MPF in fiscal 2025. The Army plans to initially build 26 vehicles, with an option to build 28 more and retrofit eight prototypes. GDLS told Defense News in an interview ahead of the Association of the U.S. Army's annual conference that it has delivered three vehicles to the Army. One is at Aberdeen Proving Ground, Maryland, going through characterization and mobility testing and preparing for firing. Another is at Yuma Proving Grounds, Arizona, undergoing desert testing and preparing for soldier training. Five more prototypes are in “some form of checkout, getting ready for their final inspection report to deliver to the government,” a GDLS spokesperson said, and the company is on track to deliver all of the vehicles this year. BAE is looking forward to the assessment because the two prototypes are so different from one another, said Jim Miller, the company's senior business development director for combat vehicles. The BAE's offering is smaller — fitting in between the Joint Light Tactical Vehicle and a Stryker in terms of size — while GDLS' vehicle is bigger, as it's based on the M1 Abrams chassis. The BAE's MPF prototype can be transported via a C-130 aircraft. Three can fit on a C-17 aircraft. And even though it is small, it has the survivability of BAE's Armored Multipurpose Vehicle, Miller said. The Army is requiring the vehicle be C-17 transportable. Soldier assessments for other recent competitions have weighed heavily into decisions, Miller added. “I think the soldier vehicle assessment is going to be really important,” he said. “Did we get this right? Now which one is closer to the mark?” https://www.defensenews.com/digital-show-dailies/ausa/2020/10/15/soldiers-to-evaluate-new-light-tank-prototypes/

    ATHENA Successfully Defends Drone Threat

    FORT SILL, Okla., Nov. 7, 2019 /PRNewswire/ -- Lockheed Martin (NYSE: LMT) recently demonstrated their laser weapon system for the U.S. Air Force at a government test range at Fort Sill, Oklahoma, where the system successfully engaged and shot down multiple fixed wing and rotary drones. The Advanced Test High Energy Asset (ATHENA) operated in a fully-netted engagement environment with a government command and control (C2) system and radar sensor. The radar track was provided to airmen who operated ATHENA via cues from the C2, then ATHENA's beam director slewed, acquired, tracked and defeated the drone with a high-energy laser. Validating this type of full kill-chain performance has been a priority of the U.S. Air Force and other branches of the Department of Defense, and it remains a requirement for laser weapons to be effective against unmanned aerial systems (UAS) on the battlefield. "We've watched in recent news this type of laser weapon solution is essential for deterring unmanned vehicle type threats, so it's an exciting time for us to watch airmen compete Lockheed Martin's critical technology. ATHENA has evolved to ensure integration and agility are key and it remains an affordable capability for the warfighter," said Sarah Reeves, vice president of Missile Defense Programs for Lockheed Martin. The ATHENA system was developed by Lockheed Martin to integrate seamlessly and provide a cost-effective, complementary anti-drone capability with the network of systems the warfighter is already using. ATHENA was operated by USAF personnel during this demonstration, and it was able to destroy multiple drones in engagements representative of what is being encountered by U.S. armed forces today. The ATHENA high-energy laser system is transportable and therefore enables the Air Force to emplace it anywhere they need to defend bases and high-value assets.
