US Army seeks new airborne tech to detect, defeat radar systems

WASHINGTON — The U.S. Army is seeking industry input on new technology allowing aircraft to survive and defeat systems in sophisticated adversarial environments made up of sensitive radars and integrated air defense systems.

A notice posted online Aug. 12 from the Army Combat Capabilities Development Command's Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance and Reconnaissance Center is asking industry for ideas ahead of an industry day in September that will provide additional information regarding the technical specifications. The service will also answer questions in depth at the event.

“The future multi-domain operational environment will present a highly lethal and complex set of traditional and non-traditional targets. These targets will include networked and mobile air defense systems with extended ranges, and long and mid-range fires systems that will deny freedom of maneuver,” the notices stated.

To maintain an advantage, the notice stated, the Army aviation community must modernize its reconnaissance, surveillance, target acquisition and lethality with an advanced team of manned and unmanned aircraft as part of its Future Vertical Lift modernization effort, which calls for a future attack reconnaissance aircraft.

The desired end state of this interconnected ecosystem will enable the penetration, disintegration and exploitation of an adversary's anti-access/area denial environment comprised of an integrated air defense system as well as surveillance and targeting systems, command-and-control capabilities, and communications technology. It will do this through a series of air-launched effects, which are a family of large and small unmanned or launched systems capable of detecting, identifying, locating and reporting threats while also delivering nonlethal effects.

Some of the sensors described include those that can passively detect and locate threats within the radio frequency/electro-optical/infrared spectrums, active detection, electronic or GPS-based decoys, and sensors able to disrupt the detection of friendly systems through cyberspace or the electromagnetic spectrum.

The notice lists five technology areas of interest:

  1. Hardware for the mission payloads.
  2. Hardware, software or techniques for distributed collaborative teaming capabilities to include processing technologies, cyber protection and data links to enable command and control of air-launched effects.
  3. Software or algorithms that can fuse, process, decide and act on sensor data allowing air-launched effects to autonomously react and adapt to countermeasures.
  4. Multimode/multifunction technologies consisting of payloads for synthetic aperture/moving target indicator radar or combined electronic warfare, radar and communication functions that share common apertures.
  5. Modular open-systems architecture.

    Navy Awards Ingalls 6 Destroyers, Bath Iron Works 4 in Multiyear Deal; Ingalls to Build Both 2018 Ships

    By: Megan Eckstein The Navy awarded six of its next Arleigh Burke-class destroyers to Ingalls Shipbuilding and four to General Dynamics Bath Iron Works, in a combined $9-billion purchase right at the end of the fiscal year. The two companies had been competing for work in a five-year multiyear procurement (MYP) deal that would cover at least 10 Flight III destroyers. The contracts span Fiscals Years 2018 – which ends on Sunday – through 2022. “These contract awards are further evidence of the Navy's continued delivery of lethal capacity to the nation with a sense of urgency while ensuring best value for the taxpayer,” Navy acquisition chief James Geurts said in a Navy news release. “The Navy saved $700 million for these 10 ships by using multiyear procurement contracts rather than a single year contracting approach. We also have options for an additional five DDG 51s to enable us to continue to accelerate delivery of the outstanding DDG 51 Flight III capabilities to our Naval force. We executed this competition on a quick timeline that reflects the urgency in which the Navy and our industry partners are operating to ensure we meet the demands of the National Defense Strategy.” Ingalls Industries' contract is worth $5.1 billion and covers two ships in FY 2018 and one a year in FY 2019 through 2022. It also includes options for additional ships, which may be subject to a future competition with BIW. Bath Iron Works' contract is valued at $3.9 billion and covers one ship a year in 2019 through 2022 – and none in the short-term in 2018. According to the Navy statement, “each shipbuilder's contract contains options for additional ships in FY18/19/20/21/22, providing the Navy and/or Congress flexibility to increase DDG 51 build rates above the 10 MYP ships in the Navy's FY 2018 budget request, if appropriated.” Lawmakers in the House and Senate armed services committees have pushed for faster acquisition of the destroyers, and in the FY 2018 National Defense Authorization Act they authorized the Navy to enter into a multiyear procurement contract with the two builders for as many as 15 destroyers – three a year, compared to the previous shipbuilding rate of two a year. The lawmakers on the appropriations committees only provided money to buy two ships in 2018, but they did fund three DDGs in the 2019 spending bill, which the Senate passed last week and the House passed this week. It is unclear if that third ship in FY 2019 would have to be competitively awarded or if the Navy would be allowed to select a shipyard based on schedule, performance or other factors – the contract announcement notes the options “may” be subject to a competitive process. Program officials had been mum during the competition on their acquisition strategy and how to handle options for additional ships. All the ships covered under this pair of contracts is for the Flight III configuration, which is built around the powerful AN/SPY-6(v) Air and Missile Defense Radar. “This procurement will efficiently provide Integrated Air and Missile Defense capability for our future fleet while strengthening our critical shipbuilding and defense industrial base,” DDG-51 program manager Capt. Casey Moton said in the news release. “The Navy is proud to be working alongside the dedicated shipbuilders at BIW and Ingalls to continue to deliver these warships to the fleet.” Moton told USNI News in a December 2017 interview that the contracts would be structured in such a way that additional ships – beyond the previous two-a-year rate – could be added easily if the Navy deemed it a priority in its spending request or if lawmakers wanted to add in more funding. With this contract award, the two shipyards – who, for a time after the production line had restarted remained neck-and-neck on contract awards and deliveries – will further diverge. Ingalls Shipbuilding was awarded a contract in June 2017 to begin work on its first Flight III ship, DDG-125. Two months later, Bath Iron Works was awarded a contract that would have the yard build DDG-126 with a Flight III configuration but DDG-127 in the older Flight IIA design, like the rest of the ships in the previous multiyear procurement contract. Though Navy and congressional officials would not comment while the competition was occurring, Bath Iron Works had been challenged to balance the Arleigh Burke-class program and the DDG-1000 Zumwalt-class destroyer program. Keeping DDG-127 – which Congress incrementally funded in FY 2016 and 2016 – at the Flight IIA design would help ease the yard into Flight III production. The yard will not be building any new destroyers in FY 2018, according to the contract announcement, whereas Ingalls will take on two Flight III ships. https://news.usni.org/2018/09/27/navy-awards-ingalls-6-destroyers-bath-iron-works-4-in-multiyear-deal-ingalls-to-build-both-fy-2018-ships

    Bell V-280 flies autonomously for first time

    By: Jen Judson ARLINGTON, Texas — The Bell V-280 Valor tiltrotor demonstrator flew autonomously for the first time Dec. 18 at the company's Arlington facility in two sorties. Over the course of the day, the V-280 met all of Bell's flight goals for the aircraft's first venture into flying autonomously. The V-280 performed an autonomous takeoff, conversion into cruise mode, precision navigation to various waypoints, loiter maneuvers, conversion into vertical takeoff and landing mode and also landed autonomously, Ryan Ehinger, Bell's program manager for the V-280, told reporters at a company demonstration of the aircraft in Arlington on January 8. Army Secretary Ryan McCarthy and Rep. Kay Granger (R-Texas) attended the demonstration. While safety pilots riding in the cockpit took over between different elements of autonomous flight throughout the sorties, the V-280 completed all pre-programmed elements “without issue,” Paul Wilson, the program's chief engineer, said. The company has yet to determine future flight tests as part of a continued effort to advance the tiltrotor's autonomous flight capabilities or whether it might specifically conduct a flight where all autonomous elements are stitched together without pilot intervention in between each maneuver. Bell developed its objective in late 2018 to run autonomous flight demonstrations with the V-280 and, just a year later, was able to execute the flight tests. The V-280 was built for the Army's Joint Multi-Role Technology Demonstration and had its maiden flight in December 2017. The autonomous flight took place on the second anniversary of the aircraft's first flight. The JMR-TD program is meant to inform the Army's Future Long-Range Assault Aircraft (FLRAA) program. A Sikorsky-Boeing team is also flying a demonstrator — the SB-1 Defiant — as part of the program but got off to a late start, flying for the first time in March 2019, mostly due to delays related to issues building the rotor blades for the coaxial helicopter. The Army is planning to modernize its fleet through an ambitious effort to acquire two new Future Vertical Lift (FVL) aircraft — FLRAA and a Future Attack Reconnaissance Aircraft (FARA) — back-to-back. The service intends to field FLRAA by FY30 following a full-and-open competition. The Army wants both FLRAA and FARA to be optionally piloted aircraft, but whether that capability comes in the first tranches when the fleet is fielded remain to be seen. Bell told reporters at the demonstration that since its first flight two years ago, the V-280 has logged over 160 flight hours among seven test pilots. It has demonstrated it can fly over 300 nautical miles in one trip and proven it can do 2G acceleration turns, can climb to 11,500 feet and has reached speeds of over 280 knots. The V-280 flew at 200 knots during the January 8 demonstration and performed other agility maneuvers while showing off its hover performance. While the JMR-TD phase is over, Bell continues to consider what could still be demonstrated with the V-280 before the aircraft is officially put to bed. https://www.defensenews.com/land/2020/01/09/bell-v-280-flies-autonomously-for-first-time

  • Space Development Agency confirms SpaceX, L3Harris awards following protest

    Space Development Agency confirms SpaceX, L3Harris awards following protest

    Nathan Strout WASHINGTON — Following a protest by Raytheon Technologies, the Space Development Agency has reevaluated awards it made for eight satellites capable of tracking hypersonic weapons, opting to stick with its original vendors: SpaceX and L3Harris. “The reevaluation confirmed the original selection decision announced in October and concluded that [SpaceX] and L3Harris Technologies' proposals offered the best value to the government,” said SDA spokesperson Jennifer Elzea in a Jan. 7 statement. The agency initially announced contracts Oct. 5 for the eight satellites. L3Harris and SpaceX were awarded $193 million and $149 million respectively to each design and develop four satellites equipped with wide field of view (WFOV) overhead persistent infrared (OPIR) sensors. Those satellites would make up the agency's inaugural tracking layer, a low Earth orbit constellation capable of detecting and tracking ballistic and hypersonic weapons. Shortly thereafter, competitors Raytheon Technologies and Airbus U.S. Space and Defense individually filed protests against the award with the Government Accountability Office. A stop work order was put in place, preventing L3Harris and SpaceX from moving forward with the contracts. In response to the protests, SDA elected to reevaluate proposals. Raytheon filed another protest Dec. 17 claiming the agency's corrective was inadequate, but the GAO dismissed that action as premature. SDA completed its reevaluation in late December, confirming its original awards, and on Dec. 28 the stop work order was lifted. “SDA is confident that reevaluation resulted in a fair outcome for all involved parties,” said Elzea. “The agency continues to make all efforts to keep the tracking layer of the National Defense Space Architecture on schedule.” In dismissing Raytheon's protest as being premature, GAO did note that the company could still protest the agency's actions following the corrective action. Neither Raytheon nor Airbus immediately responded to inquiries as to whether they would file more protests. Back in October, SDA Director Derek Tournear told C4ISRNET the contracts were the result of a full and open competition based purely on technical merit. “SpaceX had a very credible story along that line — a very compelling proposal. It was outstanding,” he said. “They are one of the ones that have been at the forefront of this commercialization and commodification route.” In addition, “L3Harris had an extremely capable solution. They have a lot of experience flying affordable, rapid, small satellite buses for the department,” he said. “They had the plant and the line in place in order to produce these to hit our schedule.” The tracking layer is just one facet of the agency's National Defense Space Architecture, a planned mega-constellation that will eventually be made up of hundreds of satellites in low Earth orbit. SDA is using a spiral development approach to build out that constellation, by adding more satellites every two years. These eight satellites in question will be part of the first tranche, which is set to launch starting in 2022. More tracking layer satellites will be launched in later tranches. Tournear has previously stated that one of the agency's priorities is avoiding vendor lock, hosting an open competition for tracking layer satellites for future tranches. https://www.c4isrnet.com/battlefield-tech/space/2021/01/07/space-development-agency-confirms-spacex-l3harris-awards-following-protest
