Sea Hawk
Another Sea Hawk F1, "WF157", was developed into a prototype for the FB 3 standard, the initial fighter bomber variant of the type and later most common of the Sea Hawk variants. To suit this role, much of the development work went into its range of external stores, although the clearance of these for service was disrupted by a lack of Royal Navy personnel. On 13 March 1954, the first production Sea Hawk FB 3, "WF280", made its first flight. A more refined Sea Hawk FGA 4 variant followed, partially to remedy stores handling problems that had been experienced with the FB 3 variant; the first FB 4 aircraft, "WV792" conducted its first flight on 26 August 1954.
