The article has it’s share of marketing/optimistic BS, but gets more real when it mentions in passing that the missile will be ready in 2030 — 20 years from now! UK and US may not even exist in current form — 20 years from now.
Quite a lot of basic innacuracy too. Exocet has been out of service with the British for a decade, and sky shadow is a ground bombardment/anti runway weapon, not an antiship missile.
