The nonskid systems covered by this specification are military unique nonskid systems manufactured to effectively support operation of fixed-wing aircraft on the nonskid systems and durability of nonskid system on exterior surfaces of submarines. They are intended for use on general (walking) deck areas (types I through VI and composition G) on all ships and submarines; the flight and hangar decks of aircraft carriers (types I and V and compositions G and L), the flight and hangar decks of air-capable surface combatants (types I, II, V, and VI and composition G); and the flight and hangar decks of air-capable amphibious, auxiliary, and sealift ships (types I and V and composition D). Types V and VI nonskid systems exhibit greater wear resistance than other nonskid systems and may provide an extended service life. Composition D nonskid systems are lighter weight per unit area than other nonskid systems. Other specific performance parameters that affect specific nonskid system selection criteria are defined by class, grade, and application and any questions regarding the intended use of a specific nonskid system should be directed to the Naval Sea Systems Command, ATTN: SEA 05S, 1333 Isaac Hull Avenue, SE, Stop 5160, Washington Navy Yard, DC 20376-5160 or CommandStandards@navy.mil. Current stock of nonskid systems manufactured in accordance with MIL-PRF-24667C, dated 22 May 2008, may be used until depleted; future requisitions for nonskid systems should refer to the current version of this specification.
