Have you ever wondered how the P-8 Poseidon maritime patrol aircraft fleet deals with the corrosion caused by saltwater?
The information came to light after a written question was submitted in Parliament.
Kevan Jones, MP for North Durham, asked via a written Parliamentary question:
“To ask the Secretary of State for Defence, whether there is a dedicated saltwater washdown facility or capability at RAF Lossiemouth for the P-8 Poseidon maritime patrol aircraft.”
Jeremy Quin, Minister of State for the Ministry of Defence, replied:
“The Post-Flight Rinse Facility at RAF Lossiemouth for the Poseidon MRA1 uses fresh water to rinse salt spray from aircraft after completing the last flight of the day to prevent salt corrosion on the aircraft skin.
Additionally, separate facilities are available to provide a full external wash of the Poseidon aircraft as part of the standard maintenance regime for the aircraft.”
On their website, the Royal Air Force say that Boeing’s Poseidon MRA1 (P-8A) is a multi-role maritime patrol aircraft, equipped with sensors and weapons systems for anti-submarine warfare, as well as surveillance and search and rescue missions.
“The Poseidon’s comprehensive mission system features an APY-10 radar with modes for high-resolution mapping, an acoustic sensor system, including passive and multi-static sonobuoys, electro-optical/IR turret and electronic support measures (ESM). This equipment delivers comprehensive search and tracking capability, while the aircraft’s weapons system includes torpedoes for engaging sub-surface targets.”
The UK plans to operate a fleet of 9 of these aircraft, 5 have already been delivered.
