The U.S. Air Force’s plan to acquire a next-generation, stealthy, precision-attack MQ-X unmanned aerial system has a candidate with the first flight of General Atomics Aeronautical Systems’ extended second variant of its jet-powered Predator C Avenger.

The closely held flight took place Jan. 12 at the company’s Palmdale, Calif., facility. USAF, in its 2025 road map, has stated a preference for a stealth signature (but not very low observability) and long endurance (the latest Avenger can fly for 16 hr.). Predator C offers a serpentine inlet for its Pratt & Whitney engine and a ducted exhaust to shield the aircraft’s heat signature.

General Atomics is building four Avenger Cs. Starting with the second aircraft, the fuselage was extended 4 ft. for additional fuel capacity. A third aircraft is expected to fly this summer followed by the fourth by early next year.

“The Air force wants the MQ-X to operate and survive in a contested or degraded operational environment,” says Chris Pehrson, the company’s director of strategic development.

That means that competitors might substitute electronic attack and electronic warfare for some of the stealth capability. Any design would combine reduced signature, jamming self-protection and long-range surveillance.

“The kind of sensors you put on a platform can allow a greater standoff distance by looking deeper into enemy territory,” the official says. “Avenger is a jet-powered UAV, so it can fly faster and respond more quickly to time-sensitive targets and threats.”

General Atomics is pushing the flight envelope of Avenger beyond 400 kt., to almost twice the speed of the turboprop-powered, workhorse MQ-9 Reaper. It will not be highly maneuverable because it’s not a fighter, nor will it have the speed to keep up with a package of strike aircraft.

“But the speed does allow it to transit to a target area or react to pop-up threats faster,” Pehrson says. “You are looking at a trade space of endurance, altitude, speed and agility. The Avenger has wings like a powered glider so it can operate at about 50,000-55,000 feet. That’s not as high as a U-2, but it will be above most of the traffic.”

Sensors of interest for the Avenger include the Raytheon surveillance ball that is on the Reaper now and multi-spectral sensors like those on the U-2 that can broaden the amount of the electromagnetic spectrum that can be monitored for targeting and reconnaissance.

Various Air Force and Navy officials have indicated that Raytheon’s jamming variant of the Miniature Air Launched Decoy (MALD-J) is being considered as a standoff electronic attack capability for the Avenger and other aircraft involved in suppressing air defenses.

“We see both suppression and destruction of enemy air defense applications for this platform,” Pehrson says. “It could be equipped with electronic jammers and anti-radiation missiles as one option. Right now, we’re looking at about 3,000 pounds internal payload and about 3,000 pounds on external, wing-mounted hard points.”

Several hundred additional pounds of payload can be carried in the forward electronics bay. In total, it’s about a ton more than the Reaper can carry. To help cut down on the amount of data that has to be transmitted to ground stations, there are plans to do machine processing on board.

“We like to give the operator or analyst the fused, correlated, real-time situational awareness with all the sensors that we possibly can,” Pehrson says. “If you have a ground moving target indicator on the radar, you want to know with high confidence that it’s the same object you are looking at with your electro-optical or infrared sensor. If it’s also giving off a signals signature, that’s all going to be on a single display.”

The Avenger is expected to cost $15-18 million for the baseline aircraft, including sensors.

跟全球鹰有啥区别隐身的尚且被打下来,不隐身的就不会下来啦
有种再去波斯上空玩几趟

是把捕食者拍扁了
拍扁隐形乃是最新潮流

T-50开始的
蛮不错的机机,不过这玩意儿蛋蛋放哪里?难道也外挂?
机机看起来很不错。天朝那个早日批量
1500-1800万美元一架,快赶上有人驾驶战斗机了。

传说发财的内部价850W,是超过
总算还有视频可以看一看,就不费劲猜E文了。  
TG加把劲

觉得涂装很好看,很有二战德国遗风。
无人机进气道为什么大多在上方
呵呵,拍扁是隐形潮流
全球鹰的竞争者来了。
捕食者三代嘛
真贵,基本型就要1500-1800万美元。纳税人的钱啊
不来个正义联盟吗?
