Commanding Officer

Commander Chris Knowles

Notable highlights included securing the Merlin Mk2 Defensive Aids Suite and Electro-Optic upgrades within an already complex and challenging programme. Graduating from the Advanced Command and Staff Course in 2016 he returned to Navy Command in the Maritime Capability Aviation role; delivering strategic advice on future manned and unmanned aviation capabilities and drafting the Fleet Air Arm Future Strategy.


820 Naval Air Squadron's role

The primary warfighting role of 820 Naval Air Squadron is the seeking out and destruction of enemy submarines – although the Merlin’s versatility means that the unit is capable of performing any number of duties, from all-weather search and rescue operations to transporting cargo and troops.
