Heres a thought,
There are three fixed wing CG assetts employed solely on single taskings. They are not multi role.
They are all different aircraft.
If we standardise to one aircraft, -the F406- equip as per greek marpol F406 with a dinghy drop capability we solve maritime pollution control, SAR/SAL and surveillance all in one go. Beech King Air would do just as well.
Why don't we do that before some dissaffected individuals drive an LPG carrier up the thames and blow it up, -during the olympics?
Well you'll have to ask the CEO of the MCA whose more interested in trying to merge CG aircraft into fisheries aircraft and 'save money' rather than considr the security and integrity of this nation.
