Yeah you heard that right, the US almost used a British ship design which I had made earlier in the week about the Type 24 and 25 Frigates before the Warship Reddit moderators took it down due to my over posting..
Side Note: my time management isn’t good and when I’d found information on the ships, I’d want to share cause I was sure no-one had even heard of the ship….but let’s get back to ship
To remind you the US Type 24 would been armed with a single 5-inch naval gun likely the mark 42 naval gun along with two 4-cell Mark 141 Quad Launcher for 8 RGM-84 Harpoon probably the RGM-84D Harpoon while the Anti-Air Defense was two 8-cell Mark 29 Guided Missile Launcher System with 16 RIM-7 Sea Sparrow and two twin 30mm cannons likely the 30mm GCM-A03 Twin Oerlikon Anti-Air Guns.
Her Aviation Wing was to be two helicopters probably two SH-2 Seasprites as given the size of the Sea Kings might not allow two onboard, I’d say she was more than likely gonna be equipped with SH-2 Seasprites.
So why did the USN turn this down? What might have happened had the USA bought the Type 24 frigate? As the Constellation class would have been its replacement had it been built.
There are multiple reasons for starters this would have been going up against the Oilver-Hazard Perry Class Design
And as Reddit user Fantastic_1 highlighted
Most sources indicate this was a cheap export or ASW-centric design. Along with the Type 25 these exercises in design eventually rolled into the Type 23. Given the sparse details, it is really doubtful Type 24 was actually offered to the US.
No business case for the US as a customer. At the time, the US had massive shipbuilding capacity, with several combatant designs in production or beginning production in the 70s.
