The Pershore flight operations diary shows Nimrod 148 operating from there from December 1975 onwards. First noted flight on 30 December 1975.
Bill Sleigh's "Aircraft for Airborne Radar Development" says: "To accommodate the Searchwater project in a more representative aircraft during the period
following the decision to close Pershore, BAe Woodford was contracted to prepare the first Nimrod/Spey prototype XV148 for installation of Searchwater. This task was completed and
the aircraft delivered to Pershore on 23 December 1975 for installation of the radar, including modifications omitted from the contract. Nimrod XV148 operated from Pershore aerodrome
from mid 1976 until June 1977 when it was one of the last aircraft to transfer to Bedford"
