TEEJ,
Yes I know that the IN FRS51s are being upgraded. But Navaleye was talking of the here and now.
Navaleye,
The analogy with F3 and CR2 being placed into storage is hardly fair. Both types are still in service so crew, expertise and spares isn't an issue. The reason ssuch assets are retained in reserve is to allow rotation and a cheap spares source for in service types.
SHAR is being retired in toto, so it wouldn't be cost effective.
Regards,
MM
