It does seem surprisingly cheap!
They also appear to have agreed the price without having to go to a public tender, although this may be because they already have 6x 139s. It will be quite an achievement for them to get back into SAR, as they have virtually zero operational experience, having had SAR removed from them nearly 20 years ago. They have 2 or 3 pilots with previous SAR experience and the current winchcrew have zero, with all of them being recently trained.
They're also short of engineers so a lot of the maintenance will have to be contracted out.
Fun times ahead!
