Got to say I like the look of the Saab Swordfish, especially with its trendy digital camouflage, but.......
Lets have a look at some of the claims
in the glossy
Significant sonobuoy stowage
What is that number? What types of buoy? What is the usage rate against a modern submarine?
No external stores
What is the impact on range and endurance with external stores? How many torpedoes can be carried? How are those weapons kept conditioned in flight?
Superior working environment
In comparison to what? Nimrod? P-8A?
Well at least that's a step up from the P-8A!!
Swordfish might make a great peacetime platform, but not convinced of its viability in this role in wartime.
