    1. The Mk38 Mod2 produced by BAE allows the operator to track targets automatically at 10,000m while waiting for a command to fire.
    2. Rheinmetal Defence has had considerable success with its Modular Light Gun (MLG) system, which adapted for naval use the 27mm rapid-fire cannon developed for aircraft use in the late 1960s.
    3. Raytheon's Mk15 PHALANX Close-in weapon System (CIWS) has been adapted to improve its effectiveness against attacks by smaller surface craft.
    4. The compact CIWS unit utilizes a dual search and track radar, automated remote fire control systems, and a six-barrel 20mm cannon capable of 4,500 rounds per minute.
    5. The U.S. Navy also is about to start fielding the Shipboard Protection System (SPS), which is a US$2.6M set of sensors and command consoles that can greatly improve a ship's situational awareness.
    6. The MILLENIUM, developed by Oerlikion Contraves, is relatively lightweight and stealthy low radar signature cupola makes it suitable for a variety of platforms.
    7. What makes the 5-in gun, or the similar size 127mm, effective against the smaller, fast-moving threats is improved munitions and fusing.
    8. Another widely used medium-calibre gun that is considered highly effective against maneuvering surface targets is the Mkl 10 57mm Bofors.
    9. There are two aluminum spacers in the cartridges to help reduce the weight of the cartridge and to help balance it.
    10. Raytheon's Mk15 PHALANX Close-in Weapon System (CIWS) has been adapted to improve its effectiveness against attacks by smaller surface craft.
    11. The U.S. Navy's array of guns, the 5-in, 57mm, 30mm, and 20mm can all be used to defend against small boats.
    12. The U.S. Navy stated they would want to use the 5-in to deal with long range threats.
    13. NAVSEA said the Mk110 was selected by the USCG specifically to counter the small boat threat using the MK295 round.
    14. The Block IB upgrade includes a surface mode configuration by adding a forward looking infrared sensor and longer and stronger gun barrels to improve shot dispersion.
    15. The CIWS has been in service for thirty years and is installed on nearly every U.S. Surface combatant and on the ships of 22 allied navies.
