the squadron did not remain dormant for long, as it reformed on 1 January 1961 by renumbering No. 79 Squadron RAF, flying Hunter FR.10s in the low-level reconnaissance role. It re-equipped with the Hawker-Siddeley Harrier in 1970, first flying them from RAF Wildenrath in West Germany. It moved on to RAF Gütersloh in 1977. The squadron operated the Harrier until the final withdrawal of the type, receiving numerous upgrades and new versions over the years. In April 1999, the squadron left Germany to move to RAF Cottesmore. On 31 March 2010, IV Squadron disbanded and reformed as IV (Reserve) Squadron at RAF Wittering, taking over from No. 20 (R) Squadron as the Harrier Operational Conversion Unit. As a result of the 2010 Strategic Defence and Security Review, the squadron disbanded in January 2011, only to reform on 24 November 2011, when No. 19 (R) Squadron, operating the BAE Hawk T2 from RAF Valley in the tactical weapons training role, was renumbered. In March 2020, the squadron was awarded the right to emblazon a battle honour on its squadron standard, recognising its role in Bosnia during 1995.
