Yes, the Luton AR15 was new. I held the first (might have been the second) UK AR15 validation. Before that we had a temporary Cossor 787, scanner mounted on a truck, display in the radar room in the old control tower. I validated that too.
The ACR430 melted down (literary, the box of tricks below the scanner) a few months after Chernobyl. I am not sure if there was a connection.
