    Fleet Air Arm

    NATIU :

    1941 to present    


    In existence since at least 1942 as the Naval Air Radio Installation Unit., (NARIU). In the 1957 FLIGHT magazine it states - based at RNAS Lee-on-Solent (HMS Daedalus) and undertook the design and construction of aircraft electronic installations for service trials, exercises and equipment evaluation. It also provided mobile air radio and radar workshops. Reported to Flag Officer Air (Home). It worked on a number of secret projects concealed under the heading of Trial installation of various H.F, V.H.F, radar, radio compass and navigational aid equipments in various aircraft and helicopters.; At some stage it was renamed Naval Air Trials Installation Unit (NATIU) at least by 1975. NATIU drew aircraft from the fleet as required, but did have a few based aircraft, for example Wessex HU.5 XS482 and XT757.

    My Grandfather William Frederick James Salter was on the NARIU/NATIU board for 22 years from 1952 HMS Siskin - HMS Daedalus 1974
