If you are interested:
The original O'Perry class frigate is 3600 tons single shaft design. Main duty is to escort CVBG as anti-submarine.
Main gun is OTO Melara 76mm/62 Mk75 at mid-ship location, which is an odd design.
A position, as you mentioned, is armed with Mk13 launcher for Harpoon and Standard
There are also 2 Mk32 triple torpedo tubes and one Phalanx CIWS at the back just before the helicopter hanger.
The helicopter hanger provide the main teeth of the ship, 2x SH-2 LAMPS anti-submarine helipcopters
This ship is fair small, but housing 200 staff.
Since it is a single propeller shaft design, one hit may disable this ship so it is not meant to be engaged under heavy fire or to defend close air attack. The Standard is only for fleet air defense.
I do feel it is very sensible to deploy the RAM, as it can defend against anti ship surface skimming cruise missle. That OTO gun is totally useless at the mid-ship location.
On the other hand, the Spruance destroyer is a totally different ship.
It is much larger, 8000 tons, and packed with some of the best sensors in the world.
The main duty is to provide air and anti-submarine defense and can engage threats under heavy fire.
It is designed with 2 shafts with two totally seperate engine rooms. ie it is very battle damage resistance.
Almost all of them are now fitted with Mk41 VLS (vertical launch system) which can launch TLAM (Tomahawk), Harpoon. SAM is the GDC RAM usiing armoured Mk29 launchers.
Therefore it has land attack capability as well as anti-ship.
But the key of this ship is sensors, tons and tons of it.
I have been told it can "hear" someone sneeze inside a submarine over 50 miles away.
In a CVBG, this ship will be deployed at the edge of the fleet defense screen to provide maximum sensor coverage for early warning, and to engage any enemy submarine which is trying to get into torpedo range. Since it is armed to its teeth, so it is very capable to look after itself.
Of couse, it is all about money, and it is very expensive.
