The day before the official handover ($65M? I thought it was paid in trade offsets) we were at Culdrose, and the Indian brass were beside us in the Ward Room for lunch. Cooks had made umpteen different curries. An Admiral turned to us and said "I wanted fish and chips".
The contract said, everything on board at 12 noon belonged to India. Off they went with a crate of our Blue Fox Mk2 test equipment, which could never test their version. A few months later, they'd complained it didn't work, and we were told to sort it out. Contractors Working Party dispatched to India, quietly swap it and get home quick.
