  US Army moves closer to equipping an active protection system on Bradley Fighting Vehicles

  By: Jeff Martin WASHINGTON — The U.S. Army has chosen to move forward with the Iron Fist Lightactive protection system for its Bradley Fighting Vehicle, after evaluating the APS' ability to be installed on the vehicle. The Army will now install the system onto a number of Bradley vehicles for a second phase of more extensive testing and evaluation, according to a release from the industry team providing the system. That team, made up of General Dynamics Ordnance and Tactical Systems and Israeli companies IMI Systems and Elbit Systems, are working to integrate and test the system, designed to protect the Bradley from threats like anti-tank missiles, rocket propelled grenades and other weapons. Iron Fist It uses a variety of sensors and countermeasures to stop those threats before they reach the vehicle. They include a electro-optical “soft kill” jammer and a physical “hard kill” interceptor to stop threats from getting closer to the vehicles. “We are excited to move into Phase II and bring the vast capabilities of our Active Protection System to the Bradley Fighting Vehicle. We look forward to continuing to partner with the Army on advancing this important technology as well as enhancing integration capabilities across multiple Army platforms” Steve Elgin, vice president and general manager of armament and platform systems for GD-OTS, said in a statement. While the release announcing the progress in testing did not say what the next phase would look like, it could mirror the same process the Army has used to qualify and evaluate Rafael's Trophy for the Abrams tank. More advanced tests will likely be against multiple types of threats in a simulated urban environment. The decision can be seen as a vote of confidence in the system and could mean further fielding on a larger number of vehicles down the road. https://www.defensenews.com/land/2018/12/20/army-moves-closer-to-equipping-an-active-protection-system-on-bradley-fighting-vehicles

  Nuclear modernization speeding up as arms control on the brink: report

  By: Aaron Mehta   WASHINGTON — Overall nuclear warheads in the world decreased in 2019, but broad modernization efforts by the biggest nuclear countries — along with a degradation of arms control agreements around the world — could mean a dangerous mix for the future, according to an annual report from the Stockholm International Peace Research Institute, or SIPRI. The organization estimated that at the end of 2019, nine countries possessed a total of 13,400 nuclear warheads, down from the 13,865 estimated in SIPRI's previous report, which in turn was a drop from 14,465 the year before. The reductions were primarily due to numbers dropping under the New START nuclear agreement between Russia and the U.S., which experts largely expect not to be renewed at the start of the new year. Russia is the largest holder of nuclear warheads, according to SIPRI's numbers, with 6,735 total, of which 1,570 are deployed. The U.S. follows at 5,800, with 1,750 deployed. The two countries account for over 90 percent of the world's nuclear arsenal. The United Kingdom (250 total, 120 deployed) and France (290 total, 280 deployed) are the other two nations believed to have deployed nuclear warheads. China (320 total), India (150 total), Pakistan (160 total), Israel (90 total) and North Korea, (30-40 total) round out SIPRI's list. Both the U.S. and Russia are engaged in expensive, widespread modernization efforts of its nuclear arsenal. America is upgrading both its legacy nuclear warheads with new designs, as well as updating its fleet of nuclear-capable bombers, submarines and ICBMs. Earlier this year, the Pentagon deployed for the first time the W76-2, a low-yield variant of the nuclear warhead traditionally used on the Trident submarine launched missile, and early design work is being done on another new submarine launched warhead design, known as the W93. Russia, meanwhile, has spoken openly about developing hypersonic weapons that could be nuclear equipped and has invested in novel weapons such as the Status-6, an underwater drone that could be equipped with a nuclear warhead. Moscow has also vocalized new deployment plans for its weapons and on June 2 made official a policy that it may use nuclear weapons in response to a conventional attack. Those investments by the world's two nuclear superpowers come against a backdrop of the collapse of numerous arms control agreements. 2019 saw the formal end of the Intermediate Range and Shorter Range Missiles (INF) treaty, and in May the U.S. announced its intention to withdraw from the Open Skies arms control verification agreement. The last major arms control agreement between Russia and the U.S. is New START, which is set to expire in February of 2021. In recent weeks the U.S. has announced its intention to start negotiations on a new arms control agreement that would include China. However, Chinese officials have repeatedly and categorically denied that it would be willing to join such an agreement, and experts largely view any efforts to create a trilateral nuclear arms control pact as a New START replacement are non-starters, leading to widespread agreement among analyst that New START is likely doomed under the Trump administration. “The deadlock over New START and the collapse of the 1987 Soviet–US Treaty on the Elimination of Intermediate Range and Shorter Range Missiles (INF) Treaty in 2019 suggest that the era of bilateral nuclear arms control agreements between Russia and the USA might be coming to an end,” said Shannon Kile, Director of SIPRI's nuclear disarmament, arms control and non-proliferation program. “The loss of key channels of communication between Russia and the USA that were intended to promote transparency and prevent misperceptions about their respective nuclear force postures and capabilities could potentially lead to a new nuclear arms race.” https://www.defensenews.com/smr/nuclear-arsenal/2020/06/14/nuclear-modernization-speeding-up-as-arms-control-on-the-brink-report/
