Not a bit of it Vie.
I did refer to the notes I have on file from a telecon of 2012.
Vie, nobody outside of a few specialist military units, mainly in the USA, gets to use the world's best NVIS. The important thing about NVIS is not that you can see in the dark but that the Taliban don't get them. ITAR controls this and not cash.
£60k will put very good goggles on 4 civilian heads if you are in an allied country and can demonstrate the correct controls. Then there are the power supplies, some display mods and the extra warning devices required by the regulators. Chicken-feed when compared with the cost of initial and continuing training across 10 or 11 years of aviation operations.
And SAR Force aren't using the world's best NVIS either. (And the poor sods on the ground are still using grotty old kit most of the time too. Ughhh.)
