....is this pie not large enough for NG to profit or...are their endeavors better suited elsewhere?

Might be a replay of the Avenger: “We can give you what you are asking for, but not at the price you are offering.”
Einstein got it backward: one cannot prevent a war without preparing for it.

I wonder what kind of RCS is GA's proposal? If it is in the 0.1 m2 or lower range, then it is not bad for refueling purpose. Navy wants UAV to on carrier ASAP to gain basic operation experience and relieve SH sorties, while further penetration ISR or strike platform will follow.

My prediction is that X-47B will see its glorious days further down the road.

U.S. Navy Shrugs Off Northrop’s MQ-25 Snub
15 Nov 2017 James Drew

"...Darrah [Rear Adm. Mark Darrah, program executive officer for unmanned aviation and strike weapons at Navair] confirms that a down-select to one vendor for MQ-25 is expected by late summer 2018.

The development contract will deliver four aircraft for testing and evaluation. The winner must then prove themselves by delivering the promised capability on time and on budget. If successful, they could receive follow-on contracts for the production phase.

Darrah says the program of record calls for 72 aircraft capable of operating from Nimitz or Ford-class carriers.

“We want to go as fast as we can and get them out there as quickly as we can. We’re incentivizing [the contractor] to do well in the engineering and manufacturing development phase,” he says.

The only two key performance parameters are carrier integration and mission tanking. To qualify, the proposed aircraft must be capable of offloading 14,000 lb. of gas starting at 500 mi. from the carrier.

The Navy says all other design attributes are “trade space” that can be exchanged for greater performance or lower costs in other areas. Secondary attributes previously being considered, like 12 hr. of endurance, were removed. No new development is planned for this aircraft, just integration of mature, existing capabilities, including the government-furnished aerial refueling system (ARS), or buddy store.

The MQ-25 will carry an electro-optical/infrared sensor ball and have space, weight, power and cooling provisions for a potential maritime surveillance radar.

Instead of specifying how many MQ-25s will embark at a time, the Navy has told contractors how many refueling “hoses” it needs for carrier operations. The service also has provided contractors with a “spot factor” value, the maximum amount of real estate their platform can occupy on the carrier deck, including peculiar support equipment.

Darrah says many of the competitors are already working on advanced prototypes, including flying and non-flying test articles. Based on what the contractors may or may not have already shown the Navy already, he teased that people might see something flying sooner than expected after contract award.

Darrah says the tanker will not carry weapons, but future carrier-based drones might. The purpose of the MQ-25, he says, is to develop an aircraft optimized for tanking that will extend the operational range of the carrier air wing and free up Boeing F/A-18E/F Super Hornets for combat missions. “We want an aircraft design from the start to do that mission,” Darrah says. “It’s about utilizing aircraft in a more efficient way.”"

NAVAIR studies plugging MQ-25 ground system into carrier ATC
27 Nov 2017 Stephen Trimble

"As three companies continue vying for the contract to develop the MQ-25 Stingray, the US Navy is quietly making progress with the design of the carrier-based, unmanned tanker aircraft’s mission control system. The Naval Air Warfare Center’s Aircraft Division in Lakehurst, New Jersey, is polling industry sources for a vendor that can develop an interface to plug the MQ-25’s carrier- and shore-based mission control station into the aircraft carrier’s air traffic control system.

The request for information released on 22 November is a further sign that Naval Air Systems Command (NAVAIR) is laying the groundwork for the MQ-25 to be ready to enter service by the mid-2020s. Last April, NAVAIR announced that a demonstration had validated the first software build for the MD-5 unmanned carrier aviation mission control system (UMCS).

The control system is divided into two components, according to the Lakehurst center’s RFI. The MD-5A will be integrated on the navy’s fleet of aircraft carriers, directing the Boeing F/A-18E/F-sized MQ-25 during takeoffs and landings. The MD-5B will be a shore-based control system, using satellite communications to monitor and control the aircraft during the mission phase.

The MD-5A version of the UMCS must integrate with the shipboard air traffic control system (SATCC). The new interface that Lakehurst is studying would translate audio messages from a human air vehicle operator for the MQ-25 into voice-over internet protocol, so it can communicate with the SATCC. The requirements also include a system that can handle classified plaintext data as well as encrypted ciphertext...."
