The above illustration applies existing American weapon and sensor systems to our "Falkland class frigate" template.
Multi Function Towed Array AN/SQR 20.
All guns and missiles cover most bearings abeam of the ship,a narrow arc on the bow is covered by missiles,5" gun and a single Phalanx/SeaRam and a narrow arc on the stern is covered only by missiles and a single Phalanx/SeaRam but all weapons can be brought to bear on any bearing with a minimum of manoeuvering.
All of these systems are "off the shelf" or made to order non developmental items.
The only thing which needs to be designed from scratch is a new hull to put those systems in,as the British can afford to design a new 6,850 tonne frigate,it is difficult to see why the United States' Navy could not do the same.
They could even share the Royal Navy's design (though the current design needs more work,note the poor firing arcs of the Phalanx).
The end result might be a frigate looking a little like this.
The configurable deck mentioned above is a flat load bearing area with access to the sea or pierside.
It may be enclosed or open.
It has connections for communications,power,potable and waste water services.
Items may be secured here by means of tie downs built in to the deck,bolts or welds.
Although it will be most often used as a location for boats and davits,the configurable deck can carry many other items including mines,mine hunting equipment,vehicles,submersibles,accommodation,stores,cruise missiles,sensors or any other mission specific equipment which the frigate may be required to carry either temporarily or permanently.
The unusual location of the Magazine Torpedo Launch System (an alternative to the Mark 32 Surface Vessel Torpedo Tubes found on American ships) is based on the principle of,as far as is practical,keeping ordnance towards the extremities of the hull for damage control purposes as well as allowing a simple arrangement of torpedoes stored facing for'ard but launching on each beam.
That location was originally conceived as a suitable place for heavyweight torpedoes,which are not commonly carried by modern surface combatants.
