209: POINT-DEFENSE/COUNTERMEASURES SYSTEM
209.1 SYSTEM COMPONENTS AND COMPONENT PARTS
209.1.1 Discuss the basic function of the following:
a. .50 caliber mounts
Navy’s largest small arm machine gun utilized for small boat attack.
b. 25mm chaingun
Ship’s small boat and lightly armored aircraft attack weapon.
c. Close-In Weapons System (CIWS)
Close range defense for anti-ship cruise missile, fixed/rotary wing aircraft attack, and surface targets.
d. Electronic Countermeasures (ECM)
Basic rule is that for each weapon used by one side, a counter weapon will be developed by the other side (i.e. radar jammers).
e. NATO Seasparrow Missile system
Semi-active, uses input from another source (TAS MK 23). Effective range 9 miles. Rapid reaction, light weight surface to air system.
f. MK 32 GMWS (RAM)
Passive, fire and forget one transition IR to RF, uses infra red and ECM (radiation). Looks for IR/RF targets, engaging RF first then IR. Quick reacting, close in self-defense system.
USMC/VSTOL fighter attack including close air supoprt, deep air support, and anti-surface anti-air, armed reconnaissance and armed escort missons. Ordnance includes 25mm, rocket pods, air-to-air missiles, air-to-surface missiles, bombs.
