    • Detect to Engage: Detects hostile inbound targets, reports range and bearing to the TAO, and receives weapon release authority. The self-defense weapons coordinator designates targets to the weapon delivery system, which destroys the target.
    • Information Warfare: Directs forces and weapons to achieve mission goals.
    • Naval Surface Fire Support (NSFS): Provides gunfire support for troops landing or conducting operations on the beach.

    RADAR & SONAR

    • RADAR (Radio Detection and Ranging): Detects the range, bearing, speed, and altitude of air and surface contacts.
    • SONAR (Sound Navigation and Ranging): Detects range, bearing, speed, and shape of underwater objects using sound.

    SONAR Performance

    • SONAR performance is affected by temperature, pressure, salinity, and depth of water
    • Speed of sound in the ocean affects SONAR detection ranges
    • Temperature, pressure, and salinity affect speed of sound
    • Temperature is the strongest factor affecting sound performance underwater

    Weapon Casualties and Safety

    • Hang Fire: Delay in the detonation of primer/ignition charge
    • Misfire: Weapon fails to discharge rounds
    • Hot Gun: Gun barrel and chamber wall temperature has been raised through prolonged firing to the cook-off point

    • Direction: Aiming the weapon towards the target
    • Delivery: Firing of the round
    • Destruction: Detonation of the round

    Frequency Radiation Safety

    • Hazards of Electromagnetic Radiation to Ordnance (HERO): To reduce the amount of frequencies being used, high frequencies may detonate a round
    • Hazards of Electromagnetic Radiation to Personnel (HERP): Measurements must be accomplished at operator locations, personnel common areas, and entry/exit points to prevent damage;
    • Hazards of Electromagnetic Radiation to Fuel (HERF): Combustible hazards associated with fuel handling areas and operations

    Frequency Ranges

    • High Frequency (HF): 3-30 MHz
    • Very High Frequency (VHF): 30-300 MHz
