December 1984 to May 1985 turned up a continued variety of problems, failing 22 of 163 contract requirements, and 22 serious failures in operational readiness. Contrary to the Army's earlier reports, OT&E Director Jack Krings said the tests showed, "the SGT YORK was not operationally effective in adequately protecting friendly forces during simulated combat, even though its inherent capabilities provided improvement over the current Vulcan gun system. The SGT YORK was not operationally suitable because of its low availability during the tests." They measured the availability of the system at 33%, as opposed to the required 90%.

jumped for cover. Technicians worked on the problem, and the system was restarted. This time it started shooting toward the target, but fired into the ground 300 metres (980 ft) in front of the tank. In spite of several attempts to get it working properly, the vehicle never successfully engaged the sample targets. A Ford manager claimed that the problems were due to the vehicle being washed for the demonstration and fouling the electronics. In a report on the test, Easterbrook jokingly wondered if it ever rained in central Europe.

Perhaps the most surprising problem was that the 30-year-old M48 chassis with the new 20-ton turret meant the vehicle had trouble keeping pace with the newer M1 and M2, the vehicles it was meant to protect.

In
February 1984 the Defense Department sent a "cure-notice" censuring Ford Aerospace for numerous "totally unacceptable" delays in the program. In March 1984 the Army took delivery, six months late, of the first production model for testing. One of the early models was reported to have locked onto a

After the 29-month Phase One trial, Ford's entry was selected as the winner of the DIVADs contest on 7 May 1981, and given a fixed-price $ 6.97 billion development and initial production contract for deliveries at various rates.

On 27 August 1985, Weinberger killed the project after about 50 vehicles had been produced. He said, "the tests demonstrated that while there are marginal improvements that can be made in the York gun, they are not worth the additional cost-so we will not invest any more funds in the system."

However, the Bofors 40 mm L/70 cannon also had worldwide popularity and had become NATO standard back in the mid-1950s. In addition, FACC had developed a proximity-sensing round for the 40 mm, which increased probability of a kill, and the shell carried either a greater explosive charge or

Ford's prototype vehicle started demonstrating problems almost immediately. The main concerns had to do with the tracking radar, which demonstrated considerable problems with ground clutter. In testing, it was unable to distinguish between helicopters and trees. When the guns were pointed upward to

The Vulcan could react quickly enough to the fleeting targets, but its 20 mm gun had an effective range of only about 1,200 metres (1,300 yd), far shorter than the 3,000 to 5,000 metres (3,300 to 5,500 yd) range of the 9K114. While the

In spite of the bad press and development problems, the Army continued to press for the system's deployment as they had no other system in the pipeline to replace it. To add to the problems, another generation of Soviet helicopter and missile designs was pushing their envelope out to 6,000 metres

For all of these reasons, the Army developed the "Advanced Radar-directed Gun Air
