No . II ( AC ) Squadron finally became the fifth RAF Typhoon squadron on 12 January 2015 at RAF Lossiemouth after the reformation of No. 12 ( Bomber ) Squadron as a Tornado GR4 unit on 9 January . On 1 July 2015 , it was reported that Typhoons from No . II ( AC ) Squadron were training with Type 45 destroyers in an Air-Maritime Integration ( AMI ) role , conceding that the service had recently neglected the role following the decommission of the Hawker Siddeley Nimrod Maritime Patrol Aircraft . In the 2015 Strategic Defense and Security Review ( SDSR ) , it was decided to retain some of the Tranche 1 aircraft to increase the number of front-line squadrons from five to seven and to boost the out-of-service date from 2030 to 2040 as well as implementing the Captor-E AESA radar in later tranches . It was announced that Typhoons would be deployed to Malta as security for the 2015 CHOGM
