Raytheon says upgraded aircraft landing system could help Air Force in conflict zones

레이시온이 항모나 강습상륙함에 설치된 JPALS의 간이 육상형인 eJPALS를 개발했습니다. 

중국과 러시아와의 대규모 분쟁에서 기존 공군기지가 적의 공격에 취약할 수 있기 때문에 간이 야전공군기지를 설치해 병력을 분산시킬 필요성이 있는데, eJPALS는 고정익, 회전익, 무인기의 정밀착륙을 모두 도울 수 있다고 합니다. 

C-130으로 수송 가능하며 2명이 1시간 30분 이내에 설치가 가능하다고 하네요. 

Raytheon says upgraded aircraft landing system could help Air Force in conflict zones

FARNBOROUGH, England — Raytheon Technologies said its upgraded aircraft precision landing system can work on both land and at sea, helping the Air Force establish austere airfields in conflict zones.

In recent years, Raytheon’s Joint Precision Approach and Landing System, or JPALS, has helped Navy and Marine pilots precisely land on carriers and amphibious assault ships. JPALS uses GPS sensors, antennas and other equipment on ships to guide in aircraft in all types of bad weather and surface conditions.

Raytheon officials said Monday that the company’s new Expeditionary Joint Precision Approach and Landing System, or eJPALS, could help the Air Force establish a network of austere air bases to help it fight a future war against a major adversary as part of its Agile Combat Employment, or ACE, concept.

The Air Force has said that having forces concentrated in well-established bases could be a weakness in a war against a major adversary such as China. In such a conflict, the enemy could try to knock out or sideline large portions of the Air Force’s fleet with a series of cruise missile or other attacks targeting aircraft or infrastructure such as runways.

Spreading forces out at a variety of locations, including by setting up rougher and smaller bases in the field, could neutralize that threat as part of ACE.

In a briefing with reporters at the Farnborough Air Show in England, Eric Ditmars, president of secure sensor solutions for Raytheon Intelligence and Space, said eJPALS is a smaller, more versatile version of the traditional JPALS. It will help fixed-wing, rotary, and unmanned aircraft alike conduct precision landings, Ditmars said.

The systems used by eJPALS are also smaller, portable and more rugged than the old JPALS equipment, he said, so it could be flown in on a C-130 and set up by two people within an hour and a half in rougher environments, “which is really critical for our customers.”

A video posted on Raytheon’s YouTube account shows two airmen setting up an eJPALS system. It looks like a disc-shaped device on a tripod stand roughly the height of an adult, tethered to the ground.

“The beauty of eJPALS is [after two airmen set it up in an hour and a half], I can do combat operations for a few hours or days, and then pack this stuff up, fly it to a different place, set it up in 90 minutes, and I’m going again,” retired Air Force Maj. Gen. Jack McMullen, now Raytheon’s director of air superiority, said in the video. “The key to this system is the flexibility it provides to the air power strategist in this peer conflict we find ourselves in today.”

EJPALS will work in poor weather such as rain, Ditmars said, using its sensors to calculate wind speeds or other challenging factors and sending that information to the pilot for a successful, accurate landing. It can handle 50 simultaneous approaches to multiple landing sites in a 20 nautical mile radius, he said.

“We’ll be able to put this out in some really difficult environments,” Ditmars said.

And it maintains the encrypted anti-jamming datalink technology that lets aircraft maintain uninterrupted contact with the landing system, Ditmars said.

Raytheon is in the midst of the first deliveries of eJPALS to the military, and is looking for additional contracts to provide more, Ditmars said.

영국 의회 회의록에 나온 내용으로는 A400M은 이런 것도 필요 없이 그냥 내릴 수 있다는 것으로 읽히네요.

In Kabul, A400M was the thing doing the really high-end extractions when the threat was up at the end. It is also worth remembering it can do things like create its own radar instrument landing approach on to a hill strip, for example, when there is zero visibility or at night, which the C-130 cannot, so it can get into some places that a C-130 could not under certain conditions.

자체 탑재된 레이더로 정밀접근 절차를 수행할 수 있다는 것 같습니다. 하긴 저걸 설치해야 되는 지역에 저걸 나르는 항공기가 착륙을 못하면 쓸모가 없으니 헬기로 이동가능한 정도로는 줄여야겠네요..
