    BAE Systems Secures $94M Contract to Deliver Advanced Tech to Navy

    Posted on November 10, 2020 by Seapower Staff MCLEAN, Va. — BAE Systems has been awarded a five-year, $94 million single-award indefinite delivery indefinite quantity contract to deliver advanced technology capability to the U.S. Navy. Building on 40 years of support to the U.S. Navy, this award from the Naval Air Warfare Center Aircraft Division's (NAWCAD) Webster Outlying Field (WOLF) enables the company to provide engineering, test, and evaluation support for sensors as well as communication, control, and weapons systems for various manned and unmanned airborne platforms. “We are bringing new advanced technologies such as artificial intelligence and autonomy to the Airborne Systems Integration Division,” said Mark Keeler, vice president and general manager of BAE Systems' Integrated Defense Solutions business. “Our state-of-the-art digital engineering capabilities, and extensive experience in integrating airborne systems are further strengthening the warfighter's ability to meet mission requirements and ensuring combat readiness in the field.” The award recognizes BAE Systems' investments in the development of model-based systems engineering capabilities. The company's ADAMS architecture provides a digital environment for systems engineering across multidisciplinary, multi-organization teams and stakeholders. On this contract, the company will use its innovative tools and methods such as digital engineering to create the digital thread that provides full design traceability to requirements, improved collaboration, and a digital repository for the Airborne Systems Integration Division. https://seapowermagazine.org/bae-systems-secures-94m-contract-to-deliver-advanced-tech-to-navy

  • Contract award for US Air Force’s Huey replacement helicopter at risk of delay until FY20

    Contract award for US Air Force’s Huey replacement helicopter at risk of delay until FY20

    By: Valerie Insinna FARNBOROUGH, England — The U.S. Air Force's contract for a replacement to the UH-1N Huey helicopter could be delayed until fiscal 2020 unless Congress adds another $83.4 million to the program. According to a reprogramming request sent by the Defense Department to Congress, the UH-1N replacement effort is currently considered a “high risk” program due to a pre-award protest by competitor Sikorsky, a Lockheed Martin subsidiary, which was dismissed in May. The protest had temporarily put a hold source selection, deferring a contract planned for June to September. Current funds would expire at the end of the fiscal year on Sept. 30, meaning that if an award was further delayed it would take until FY20 to inject more money to continue on with the program, the request stated. Air Force Secretary Heather Wilson acknowledged in May that the contract could be awarded sometime this fall. “We're going to try and not let that slip too much because we know we need to get the Hueys replaced, but we did get a delay,” she had said. The Air Force's aging UH-1Ns are most well-known for the role they play defending nuclear missile sites, and it is the importance of this mission that has led to criticism from leaders in Congress and in the U.S. military — including U.S. Strategic Command head Gen. John Hyten — who have said the service needs to move more quickly to procure new helicopters. Three companies are competing for the Huey replacement award, with the first of a total of 84 new armored helicopters expected for delivery as early as 2020 — although if a contract is delayed until FY20 it seems likely that fielding will not be possible for another couple of years. Sikorsky is offering the HH-60U, a version of its UH-60 Black Hawk helicopter with modifications like a rescue hoist and electro-optical sensor. Sierra Nevada Corp. has pitched a modernized, life-extended version of used Army UH-60L aircraft that its calling “Sierra Force.” Meanwhile, Boeing and Leonardo are partnering on the MH-139, a militarized version of the Italian firm's civilian AW139 helicopter. Boeing submitted the final proposal for the aircraft Tuesday, it confirmed in a statement. “The Boeing MH-139 is capable, affordable, and ready to serve the United States Air Force's urgent UH-1N replacement needs,” the company said. "With a hot production line in Philadelphia, we are well-positioned to meet the USAF's delivery requirements for fielding this vital platform as soon as possible.” While the requirements for the helicopter were not made public, the Air Force has specified nine fully loaded troops without needing to be refueled for an endurance of at least 225 nautical miles. They also should be able to fly three hours while maintaining a 135-knot cruise speed. https://www.defensenews.com/air/2018/07/18/contract-award-for-air-forces-huey-replacement-helicopter-at-risk-of-delay-until-fy20

    Unmanned systems, anti-drone tech featured at South Korean arms expo

    By: Brian Kim SEOUL — Unmanned defense systems and advanced weapons to counter drone threats dominated an arms exhibition held outside of Seoul, South Korea, this week. During the biennial DX Korea event, which ran Nov. 18-20, local defense companies showcased their cutting-edge unmanned and counter-drone technologies. Hanwha Corporation, a leading developer of guided-missile technology and subsidiary of Hanwha Group, displayed its new family of laser weapons systems. The company unveiled two types of anti-drone laser weapons: one for installation on light tactical vehicles, and the other a laser-based anti-aircraft weapon gun in a container configuration. The latter, designated as Block I, can be modified to a Block II self-propelled system, but specifications were not disclosed. Hanwha Corporation is a partner in an anti-drone laser weapons development project led by the government's Agency for Defense Development. “The laser-based anti-aircraft weapon is a new concept of armament to shoot down small aerial targets, including drones and multi-copter with a light source laser,” the company said in a news release. “Prototypes of the laser weapon variants are under development jointly with the ADD.” The company also displayed anti-jamming equipment that can be fitted in tactical guided missiles as well as on military vehicles and naval vessels. Hanwha Systems — also an affiliate of Hanwha Group — displayed a mock-up of its personal air vehicle, Butterfly, under development with U.S. air taxi startup Overair. In partnership with Overair, Hanwha Systems plans to fully develop the electric vertical-takeoff-and-landing, or eVTOL, vehicle by 2040, with an eye toward military sales. “With technologies to be accrued from the development of commercial eVTOL, we will push for developing a military variant capable of conducing multiple missions, including special operations, transport and assault,” the company said in a news release. Meanwhile, Hyundai Rotem presented its HR-Sherpa unmanned ground vehicle designed to support infantry troops. The six-wheel drive vehicle can move autonomously or via remote control to perform missions such as surveillance, medical support and chemical detection. It has a payload of 600 kilograms and a combat weight of 1,800 kilograms. It is equipped with airless tires and powered by a battery with an operating time of six hours when traveling at 5 kph. LIG Nex1 showcased the third version of its Sea Sword unmanned surface vessel for riverside defense, following other naval variants. The vessel adopts a high-speed monohull design and is constructed with fiber-reinforced plastic. Equipped with a diesel engine and a waterjet propulsion system, the boat can sail at a maximum speed of 40 knots and has an operational endurance of up to eight hours at 15 knots. An indigenously developed autonomous navigation system enables the vessel to carry out surveillance and reconnaissance missions based on a preprogrammed route. Hanwha group was ranked 32nd in Defense News' list of the top 100 defense companies in the world. LIG Nex1 was ranked 68th, while Hyundai Rotem was ranked 95th. https://www.defensenews.com/industry/techwatch/2020/11/20/unmanned-systems-anti-drone-tech-featured-at-south-korean-arms-expo
