Thanks SIM,
RAP- Rocket Assisted Projectile from the navweps site; the 5 inch "RAP round had a maximum range of 23,770 yards (21,735 m)".
The 8" LRBA used by the Cruisers we have in game would be awesome as well
but they weren't developed until the late 60's.
"5) In the late 1960s the "Gunfighter" program at Indian Head Naval Ordnance Station developed Long Range Bombardment Ammunition (LRBA) projectiles. These were Arrow Shells with a body diameter of 4.125" (10.4 cm) and a fin diameter of 5.0" (12.7 cm) which were sized to be fired from 8" (20.3 cm) guns by using a sabot and obturator system. Tests with these in 1968 showed maximum ranges of 72,000 yards (66,000 m). The burster in these shells was PBX-w-106, a castable explosive. Sabot weighed 17.6 lbs. (8.0 kg) and was discarded as the projectile left the muzzle. After a test firing off Okinawa of three inert-loaded shells, USS St. Paul (CA-73) in 1970 conducted a two day bombardment mission against Viet Cong positions at ranges up to 70,000 yards (64,000 m). At the time, St. Paul was the only 8" gunned cruiser still in active service." That's over 39.5 miles away!
great source of info;
