Shack Replacement
HS800 to meet OR357 originally with RR Medway engines but reverted to RR Spey. HS800 was a buble fuselage (as Nimrod) based on the Trident. Then a new OR for Maritime was issued that almost exactly matched the Atlantic. Nimrod MR1 (HS801) was a bid put together in 7 days by HS to meet both the new OR and the Breguet price.
