## History
### Amphibious Warfare Trials Unit (1958)

728C Naval Air Squadron formed on 7 January 1958 at RNAS Lee-on-Solent (HMS Daedalus) as the Amphibious Warfare Trials Unit. It was equipped with four Westland Whirlwind HAS.22, an anti-submarine warfare variant of the helicopter. The squadron was tasked with establishing proficiency in ship to shore deployment of Royal Marines.
The helicopters were embarked in HMS Eagle and HMS Ark Royal for transit to Malta and on arrival set up headquarters at RNAS Hal Far (HMS Falcon). During April the squadron embarked in the landing ship HMS Striker (L128) for Tripoli, Libya, returned in HMS Ark Royal to RNAS Hal Far, then re-embarked for Sardinia, returning to Malta in HMS Striker.
It next embarked for RAF Nicosia, Cyprus, in June. The helicopters were carried as deck cargo in HMS Bermuda, for operations with 45 Commando Royal Marines. The squadron returned to RNAS Hal Far during July.
August saw 728C Naval Air Squadron carry out trials with HMS Surprise and in September a detachment was deployed to Libya. By the beginning of October the squadron was back at RNAS Hal Far, before becoming 848 Naval Air Squadron on 13 October.
