Study Notes
Marine Location Markers
- The Mk 58 marine location marker is activated by seawater and burns for 40 to 60 minutes.
- The Mk 6 marine location marker is preferable for man overboard drills and features a pull ring that activates a 90-second delay fuse.
- The color of the Mk 2 marine illumination signal is determined by the texture of the closing wad, burning for approximately 6 seconds.
- The Mk 13 marine smoke and illumination signal produces orange smoke and has a flame end identifiable by three beads on the plastic cap.
Pyrotechnics Safety and Handling
- Unfired signals should not remain in the Mk 5 pyrotechnic pistol as it is always cocked when the breech is closed.
- Ordnance handlers must be aware that some pyrotechnics can burn with intense heat and that moisture can make them more sensitive or difficult to ignite.
- The Navy pyrotechnics can typically withstand temperatures from 65°F to 160°F.
Ammunition and Ordnance
- Familiarity can lead to complacency, and personnel must be cautious when handling explosives.
- Ammunition classifications include fixed (small-arms), separated (two-piece assembly), drill (not for firing), and service (designed for combat).
- The Mk 79 Mod 2 personnel distress kit contains seven signals, with the Mk 79 Mod 0 providing a red star signal.
- A dented Mk 80 hand-fired signal poses a risk of violent reaction if fired.
Missile and Projectile Dynamics
- Guided missiles are classified by speed: subsonic (up to Mach 0.8), transonic (Mach 0.8 to 1.2), supersonic (Mach 1.2 to 5.0), and hypersonic (above Mach 5).
- Four principal aerodynamic forces acting on missiles in flight are thrust (forward propulsion), drag (air resistance), weight (gravity), and lift (upward force).
Fire Control and Maintenance
- The Mk 38 mod 2 has multiple firing modes, including single shot, low burst, high burst, low continuous, and high continuous.
- The MK46 mod 2 GWS features a 400-round magazine capacity with a dual-feed mechanism, firing at 200 rounds per minute.
- The purpose of the daily magazine inspection is to monitor temperature and ensure proper conditions for ammunition storage.
Regulatory Compliance and Documentation
- Each family group of ammunition requires certification on the 8020/5 form, which must be signed by the board chairman, board members, and the individual being certified.
- The CAIMS manual lists the types and quantities of ammunition authorized for issue on specific ships.
- The MIL-STD 129 color tags indicate the status of ammunition: yellow for serviceable, green for repairable, red for unserviceable, etc.
Reporting and Incident Management
- OPREP-3 Navy Blue incident reports are required for specific incidents involving significant quantities of weapons or ammunition and significant occurrences like armed robberies or terrorist involvement.
- Non-government AA&E (personal weapons) storage is authorized by the commanding officer and must be separate from government AA&E storage.
Bearings and Navigational Insignias
- Bearings are classified as relative, true, or magnetic, and measured in degrees from 000° to 360°.
- Boats for personal use by officers or with civil officials on official business display special flagstaff insignias.### Flagstaff Devices
- Spread Eagle: Used for civilian officials or flag officers with an official salute of 19 guns or more.
- Halbert: Designated for flag or general officers with salutes less than 19 guns, or civil officials with salutes between 11 and 19 guns.
- Ball: For officers of captain rank or equivalent in the Navy, and certain diplomatic officials.
- Star: Indicates officers of commander rank or equivalent.
- Flat Truck: For officers below commander grade and civil officials with lesser honors.
Civil War Battle of Mobile Bay
- Admiral Farragut commanded the U.S. Navy during the Civil War.
- Famous order: "Damn the Torpedoes! Full speed ahead."
Advantages of Nylon Line
- Strength: Nylon is 2.5 times stronger than natural fiber lines.
- Elasticity: Offers greater strength and elasticity than natural fibers.
- Weather Resistance: Superior resistance to weather conditions.
HE-CVT Round Purpose
- The HE-CVT round creates an air burst over land or water using an active radio frequency fuze.
Combat Systems Alignment (CSA)
- CSA ensures correct alignment and direction for combat system equipment and elements.
Definitions: Misfire, Hangfire, Cookoff
- Misfire: Complete failure to fire; may resemble a hangfire or delay in firing mechanism. Caution is necessary before opening the bolt.
- Hangfire: Delay in the propelling charge; unpredictable duration. A prescribed time must be observed before opening the bolt.
- Cookoff: Occurs when a hot weapon causes the round to fire without a trigger pull. Immediate action is needed for rounds in a hot weapon to prevent unintended firing.
