Correct. There was the aircraft fit, carrier fit, and transportable ground installation.
Phase 2 was the Near Field Integrity Monitoring System, and Microwave Dummy Deck Landing System. The latter was short lived, someone reversing a 4-tonner over it at Yeovilton.
It's a long story, but around 1992 the FAA decided not to retain it. A strange decision, given a Board of Inquiry had recently noted the aircraft hadn't MADGE fitted, the pilot having difficulty getting home after a bird strike. But the president wasn't able (or allowed) to publish the background.
