Jeff (sorry), just curious if you factored in the enhanced air-defence of the 76mm guns on the Horizons? I mean the OTO-Melara 'smart' rounds such as the Davide which it seems is pretty much a dead cert though still labelled as "under development" by OTO-M on their site:
It sounds a very impressive system to me, must be much cheaper than RAM or Mistral units.
A typical OTO-M 76mm gun mount has 80 ready to fire rounds, so assuming (conservatively) 4 rounds per engagement, each gun mount could engage 20 targets before reload minus any non-smart rounds in the ready to fire magazine.
I'm pretty sure that the Horizon's 76mm guns are primarily meant for air defence not shore bombardment and with anti-ship close in defence secondary also.

DAVIDE System represents the evolution of the 76/62 Gun for employment as an inner layer antimissile defence system.
It provides the gun with the capability to defeat supersonic or subsonic missiles, seaskimming or diving.
It has been conceived as an add-on equipment, to allow retrofitting on the in-service 76/62 Super Rapid or Compact Gun Mounts.
DAVIDE System provides an RF guidance link to the projectiles in flight.
DART (Driven Ammunition Reduced Time of flight) is the smart ammunition fired and guided by the DAVIDE System.
A sub-calibre guided projectile with canard control and with high terminal manoeuvrability.
Guidance system characteristics:
* No limitation to number of projectiles in flight
* Data link to the projectiles
* All-weather
Projectile main characteristics:
* Full compatibility with existing 76/62 gun and FCS
* Proximity programmable digital microwave fuze
* Notched warhead
* Effective range > 5 Km
Fuze main characteristics:
* Radial sensitivity: > 10 m
* Operating altitude (above sea level): down to 2 m
* High reliability
* Burst point optimization
System performance:
* High effectiveness against all missile and aircraft threats
* Secondary role against small fast patrol boats
* Average number of rounds per engagement = 3
