  What Might DARPA’s Longshot Fighter Drone Be Armed With?

  It appears that the new drone will come with an upgraded, or perhaps new, advanced air-to-air missile. by Kris Osborn The prospect of new drone-fired air-to-air weapons, such as those being introduced in DARPA's LongShot effort, raise impactful tactical questions regarding the nature of air warfare moving into future decades. The DARPA program is invested in engineering a new kind of aerial attack drone configured such that it can integrate a new generation of air-to-air weapons potentially changing or at least impacting existing aerial warfare paradigms. The Pentagon's DARPA just awarded LongShot development deals to Northrop Grumman, Lockheed and General Atomics to explore concepts, computer modeling and design options for a new air-attack platform. “Current air superiority concepts rely on advanced manned fighter aircraft to provide a penetrating counter air capability to effectively deliver weapons. It is envisioned that LongShot will increase the survivability of manned platforms by allowing them to be at standoff ranges far away from enemy threats, while an air-launched LongShot UAV efficiently closes the gap to take more effective missile shots,” DARPA writes in a statement on the program. What kinds of technologies and air-attack systems are likely to characterize future warfare in the skies? Clearly the intent of the DARPA program, which is early on and primarily in a conceptual phase, is to break existing technical barriers and architect weapons which advance the attack envelope well beyond simply upgrading existing weapons. This sets the bar quite high, given that the current state of upgraded air-to-air weapons is increasingly more advanced. The AIM-9X, for example, has been upgraded to accommodate what's called “off-boresight” targeting wherein a missile can engage a target to the side or even behind the aircraft it launches from. Off boresight capable AIM-9X missiles are now arming F-35s, bringing a new ability to fire course-changing air-to-air weapons at angles beyond direct line-of-sight. Weapons upgrades to the F-22 as well, brought to fruition through a Lockheed software upgrade called 3.2b, brings new upgrades to the AIM-9X and AIM-120D. Raytheon data explains that a Block 2 AIM-9X variant also adds a redesigned fuze, new datalink to support beyond visual range engagements, improved electronics and a digital ignition safety device. Another part of the weapons upgrade includes engineering the F-22 to fire the AIM-120D, a beyond visual range Advanced Medium-Range Air-to-Air Missile (AMRAAM), designed for all weather day-and-night attacks. It is a “fire and forget” missile with active transmit radar guidance, Raytheon data states. The AIM-120D is built with upgrades to previous AMRAAM missiles by increasing attack range, improving seeker guidance GPS navigation, inertial measurement units and a two-way data link, Raytheon statements explain. Air-to-Air weapons are also being upgraded with new “countermeasures” to, among other things, enable guidance systems to stay locked on target even in a “jamming” environment. For example, adversaries are increasingly engineering electronic warfare weapons intended to find and “jam” radio frequency or infrared targeting technologies used in air-to-air weapons. Technical efforts to “counter” the countermeasures with frequency-hopping adaptations can enable electronically guided weapons to sustain a precision trajectory despite enemy jamming attempts. These kinds of innovations might, at least initially, be providing a technical baseline from which new weapons can be envisioned, developed and ultimately engineered. The new air-to-air weapons intended for LongShot will most likely not only be much longer range but also operate with hardened guidance systems, flexible flight trajectories, advanced countermeasures, a wider range of fuze options and newer kinds of explosives as well.

  Boeing-Leonardo Team Scoops Up $2.38B UH-1N Replacement Deal

  By COLIN CLARK The head of Strategic Command must be very happy this evening, having learned that the Air Force is finally buying a new helicopter to guard America's ICBM fields. The Boeing-Leonardo team won the contract to supply 84 helicopters. WASHINGTON: The head of Strategic Command must be very happy this evening, having learned that the Air Force is finally buying a new helicopter to guard America's ICBM fields. The Boeing-Leonardo team won the contract to supply 84 helicopters. UPDATE BEGINS “The award of this contract is great news; today is a good day,” Gen. John Hyten, commander of U.S. Strategic Command said in a statement. “I've been vocal about the need to quickly replace the UH-1N, which is an important part of our multi-layered ICBM defense system. Awarding this contract is a huge step in the right direction in ensuring our Nation's nuclear deterrent remains safe, secure, effective, and ready. I'm grateful to the Air Force and Congress for prioritizing the UH-1N replacement.” UPDATE ENDS Here's how strongly Hyten felt: “Of all the things in my portfolio, I can't even describe how upset I get about the helicopter replacement program,” he told the Senate Armed Services Committee in April 2017. “It's a helicopter, for gosh sakes. We ought to be able to go out and buy a helicopter and put it in the hands of the people that need it. And we should be able to do that quickly.” The helicopters will execute a range of missions, including moving security crews in the event of threats to our nation's ICBM fields, escorting convoys moving nuclear weapons, flying senior government officials out of the capital in the event of an emergency and providing support to the US Embassy in Japan. The Air Force, clearly happy to be putting this tortured acquisition behind them, quoted Air Force Secretary Heather Wilson claiming the deal saved taxpayers $1.7 billion over the service's original estimate of $4.1 billion, thanks to “strong competition.” When Boeing, the prime on the program, showed the helicopter off to reporters last year executives stressed it would save the US taxpayer $1 billion. Lockheed Martin also bid for the program, offering its HH-60U. This evening's contract award of $375 million is for the first four helicopters and includes the integration of non-developmental items. The fixed price contract pays for up to “84 MH-139 helicopters, training devices, and associated support equipment.” The MH-139 has five rotor blades, which, with their tapered ends, significantly reduce the amount of vibration. The helicopter was also noticeably quieter than most of its conventional military competitors. We flew up to 150 knots and it felt as smooth as a large Mercedes sedan on the highway. The helicopters, based on Leonardo's commercial AW139 helicopter, will be assembled by the Italian company at its northeast Philadelphia plant. Boeing will integrate military components at its facility south of Philly. https://breakingdefense.com/2018/09/boeing-leonardo-team-scoops-up-2-38b-uh-1n-replacement-deal/
