US Navy's POV on the UCLASS Requirements

It’s crunch time for UCLASS. On September 10th — after multiple delays — the Pentagon’s top weapons buyer and his Defense Acquisition Board will sit in judgment on the proposed combat drone. The question: how best to bring the robot revolution to the deck of the 90-year-old aircraft carrier.

The “Unmanned Carrier-Launched Airborne Surveillance and Strike” aircraft is most controversial and high-stakes component of the Navy’s multi-front strategy to employ drones alongside– not replacing — traditional piloted aircraft. Land-based, long-range patrols will use the MQ-4C Triton (derived from the Air Force Global Hawk) alongside the manned P-8A Poseidon. Small surface warships like the Perry-class frigate and the Littoral Combat Ship will use the MQ-8C Fire Scout unmanned helicopter alongside SH-60 Sea Hawks. But UCLASS will fly from the Navy’s thousand-foot-long flagships, its nuclear-powered aircraft carriers, multi-billion-dollar ships whose strategic value depends on the planes they carry.

Vocal critics in Congress and quieter ones inside the Pentagon contend that the Navy has dumbed down its specifications for UCLASS, turning it from a robotic stealth bomber into a modestly armed scout drone. Navy officials counter that the design will “be able to grow” from the technically achievable, fiscally affordable scout that enters service ca. 2021 into a high-end war machine.

The Navy hasn’t changed its requirements for UCLASS, it’s just “refined” them to reflect “the art of the possible” given current technology, said Rear Adm. Mat Winter, head of unmanned aviation at the Naval Air Systems Command (NAVAIR).

“We’ve gone back and forth with industry to make sure, ‘is this the art of the possible?,” the admiral told reporters Sunday after flight tests of a prototype carrier-launched drone, the X-47B. “That’s what the last nine months have been [about]. Warfighter requirements for UCLASS have been stable since April 2013, when the Chief of Naval Operations signed the CDD [Capability Development Document]. The design requirements had been continually refined to ensure that we had a technically feasible solution.” (Emphasis mine).

Everyone wants to give the warfighters the best technology they can, but “we don’t want to provide something to industry that we technically can’t accomplish,” Winter went on. “Survivability, payload, and endurance” form an “iron triangle” of inevitable tradeoffs, he said. (The Navy’s desire for a fuel-efficient UCLASS with big gas tanks to do long reconnaissance patrols, in particular, wars with maximizing bombload, speed, and stealth for strike missions).

“There’s a requirement to operate UCLASS in a permissive environment” — that is, one without an anti-aircraft threat — “but be able to grow to a non-permissive [one]” where it needs high-end stealth and other countermeasures to avoid detection and destruction, Winter said. “Engineers have got turn that into, what, frequency spectrums and threats and squeaks and beeps, because we’ve got to be able to truly quantify what that is. ”
