BRP General Mariano Alvarez (PS-38)
BRP ''General Mariano Alvarez'' (PS-38) is the lone ship of its class of coastal patrol ships in service with the Philippine Navy. She was the lead ship of the US Navy's prior to being transferred to the Philippine Navy. History Launched as the first of fourteen ships of the , the primary mission of was to serve as a platform for conducting maritime special operations, including interdiction, escort, noncombatant evacuation, reconnaissance, operational deception, intelligence collection, and tactical swimmer operations. Her small size, stealthy construction and high speed were tailored to performing long-range Special Operations Forces (SOF) insertion and extraction as well as other SOF support duties as needed. As good a design as it is, ''Cyclone'' had barely gone into service in the mid-1990s when the Special Operations Command rejected them as too big for commando missions, and the regular surface Navy dismissed them as too small for any of its missions. The Navy began l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclone
In meteorology, a cyclone () is a large air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above (opposite to an anticyclone). Cyclones are characterized by inward-spiraling winds that rotate about a zone of low pressure. The largest low-pressure systems are polar vortices and extratropical cyclones of the largest scale (the synoptic scale). Warm-core cyclones such as tropical cyclones and subtropical cyclones also lie within the synoptic scale. Mesocyclones, tornadoes, and dust devils lie within smaller mesoscale. Upper level cyclones can exist without the presence of a surface low, and can pinch off from the base of the tropical upper tropospheric trough during the summer months in the Northern Hemisphere. Cyclones have also been seen on extraterrestrial planets, such as Mars, Jupiter, and Neptune. Cyclogenesis is the process of cyclone formation and ...

FIM-92 Stinger
The FIM-92 Stinger is an American man-portable air-defense system (MANPADS) that operates as an infrared homing surface-to-air missile (SAM). It can be adapted to fire from a wide variety of ground vehicles, and from helicopters as the Air-to-Air Stinger (ATAS). It entered service in 1981 and is used by the militaries of the United States and 29 other countries. It is principally manufactured by Raytheon Missiles & Defense and is produced under license by Airbus Defence and Space in Germany and by Roketsan in Turkey. Description The FIM-92 Stinger is a passive surface-to-air missile that can be shoulder-fired by a single operator (although standard military procedure calls for two operators, team chief and gunner). The Stinger was intended to supplant the FIM-43 Redeye system, the principal difference being that, unlike the Redeye, the Stinger can acquire the target when the target approaches the operator, giving much more time to acquire and destroy the target.

Mk 19 Grenade Launcher
The Mk 19 grenade launcher (pronounced Mark 19) is an American 40 mm belt-fed automatic grenade launcher that was first developed during the Vietnam War. Overview The Mk 19 is a belt-fed, blowback-operated, air-cooled, crew-served, fully-automatic weapon that is designed not to cook off. It fires 40 mm grenades at a cyclic rate of 325 to 375 rounds per minute, giving a practical rate of fire of 60 rounds per minute (rapid) and 40 rounds per minute (sustained). The weapon operates on the blowback principle, which uses the chamber pressure from each fired round to load and re-cock the weapon. The Mk 19 can launch its grenade at a maximum distance of , though its effective range to a point target is about , since the large rear leaf sight is only graduated as far. The nearest safe distance to launch the grenade is 310 meters in training and 75 meters in combat. Though the Mk 19 has a flash suppressor, it serves only to save the eyesight of its operat ...

50 BMG
The .50 Browning Machine Gun (.50 BMG, 12.7×99mm NATO and designated as the 50 Browning by the C.I.P.) is a caliber cartridge developed for the M2 Browning heavy machine gun in the late 1910s, entering official service in 1921. Under STANAG 4383, it is a standard service cartridge for NATO forces as well as many non-NATO countries. The cartridge itself has been made in many variants: multiple generations of regular ball, tracer, armor-piercing (AP), incendiary, and saboted sub-caliber rounds. The rounds intended for machine guns are made into a continuous belt using metallic links. The .50 BMG cartridge is also used in anti-materiel rifles. A wide variety of ammunition is available, and the availability of match grade ammunition has increased the usefulness of .50 caliber rifles by allowing more accurate fire than lower quality rounds. History In response to the need for new anti-aircraft weaponry during World War I, John Browning developed the .50 BMG. He wanted the ...
