USS Makin Island (LHD-8)
USS ''Makin Island'' (LHD-8), a , is the second ship of the United States Navy to be named for Makin Island, target of the Marine Raiders' Makin Island raid early on in the United States' involvement in World War II. ''Makin Island''s task is to embark, deploy, and land elements of a Marine Corps landing force in an amphibious assault by helicopters, landing craft, and amphibious vehicles. The secondary or convertible mission for ''Makin Island'' is sea control and power projection. Design and construction ''Makin Island'' is the eighth ship of the ''Wasp'' class, but features noteworthy technological advances. Changes from the previous LHD design include gas turbine main propulsion engines, all-electric auxiliaries, an advanced machinery control system, water-mist fire-protection systems, and the Navy's most advanced command and control and combat systems equipment. The new propulsion system allows the engines to be directly controlled from the throttles on the bridge, replac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Landing Craft Air Cushion
The Landing Craft Air Cushion (LCAC) is a class of air-cushioned landing craft (hovercraft) used by the United States Navy and the Japan Maritime Self-Defense Force (JMSDF). They transport weapons systems, equipment, cargo and personnel from ship to shore and across the beach. It is to be replaced in US service by the Ship-to-Shore Connector (SSC). Design and development Two prototypes were built; JEFF A by Aerojet General in California, JEFF B by Bell Aerospace JEFF A had four rotating ducted propellers JEFF B had two ducted rear propellers similar to the proposed SK-10 which was derived from the previous Bell SK-5 / SR.N5 hovercraft tested in Vietnam. JEFF B was selected for the LCAC.LCAC U.S. Navy Fact File JEFF A was later modified for Arctic use and deployed in Prudhoe Bay to support offsh ...

RIM-116 Rolling Airframe Missile
The RIM-116 Rolling Airframe Missile (RAM) is a small, lightweight, infrared homing surface-to-air missile in use by the German, Japanese, Greek, Turkish, South Korean, Saudi Arabian, Egyptian, Mexican, UAE, and U.S. Navies. It was originally intended and used primarily as a point-defense weapon against anti-ship missiles. As its name indicates, RAM rolls as it flies. The missile must roll during flight because the RF tracking system uses a two-antenna interferometer that can measure phase interference of the electromagnetic wave in one plane only. The rolling interferometer permits the antennas to look at all planes of incoming energy. In addition, because the missile rolls, only one pair of steering canards is required. , it is the only U.S. Navy missile to operate in this manner. The Rolling Airframe Missiles, together with the Mk 49 Guided Missile Launching System (GMLS) and support equipment, make up the RAM Mk 31 Guided Missile Weapon System (GMWS). The Mk-144 Guided M ...

Tactical Air Navigation System
A tactical air navigation system, commonly referred to by the acronym TACAN, is a navigation system used by military aircraft. It provides the user with bearing and distance (slant-range or hypotenuse) to a ground or ship-borne station. It is a more accurate version of the VOR/ DME system that provides bearing and range information for civil aviation. The DME portion of the TACAN system is available for civil use; at VORTAC facilities where a VOR is combined with a TACAN, civil aircraft can receive VOR/DME readings. Aircraft equipped with TACAN avionics can use this system for en route navigation as well as non-precision approaches to landing fields. The Space Shuttle is one such vehicle that was designed to use TACAN navigation but later upgraded with GPS as a replacement. The typical TACAN onboard user panel has control switches for setting the channel (corresponding to the desired surface station's assigned frequency), the operation mode for either transmit/receive (T/R, to get ...

AN/SPN-35
The AN/SPN-35 is a computerized automatic landing system installed on the Tarawa-class amphibious assault ship and other LHA/LHD-class warships to give control for aircraft during the final approach and landing. The Joint precision approach and landing system, Joint precision approach and landing system (JPALS) is slated to replace the AN/SPN-35 on U.S. Navy amphibious assault ships. Description The AN/SPN-35 is used to offer guidance to the aircraft pilot on final approach. It provides relative azimuth, range, and elevation information to the radar operator, who relays this as verbal guidance to the aircraft pilot on approach. The AN/SPN-35A variant has two antennas: the azimuth antenna (AS-1292/TPN-8) and the elevation antenna (AS-1669/SPN-35). The azimuth antenna is located above the azimuth drive assembly on the stabilized yoke. The elevation antenna is mounted on the elevation drive assembly adjacent to the azimuth antenna. History The AN/SPN-35 was developed from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

AN/SPS-67
The AN/SPS-67 is a short-range, two-dimensional, surface-search/navigation radar system that provides highly accurate surface and limited low-flyer detection and tracking capabilities. History The AN/SPS-67 is a solid-state replacement for the AN/SPS-10 radar, using a more reliable antenna and incorporating standard electronic module technology for simpler repair and maintenance. The AN/SPS-67 provides excellent performance in rain and sea clutter, and is useful in harbor navigation, since the AN/SPS-67 is capable of detecting buoys and small obstructions without difficulty. The AN/SPS-67(V)1 radar is a two-dimensional (azimuth and range) pulsed radar set primarily designed for surface operations with a secondary capability of anti-ship-missile and low flier detection. The radar set operates in the 5450 to 5825 MHz range, using a coaxial magnetron as the transmitter output tube. The transmitter/receiver is capable of operation in several pulse width settings: a long (1.0 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AN/SPS-48
The AN/SPS-48 is a US naval electronically scanned array air search three-dimensional radar system manufactured by ITT Exelis and deployed in the 1960s as the primary air search sensor for anti-aircraft warships. The deployment of the AN/SPY-1 and the end of the Cold War led to the decommissioning of many such ships, and many of these vessels AN/SPS-48 sets were reused on aircraft carriers and amphibious ships, where it is used to direct targets for air defense systems such as the Sea Sparrow and RIM-116 SAM missiles. Existing sets are being modernized under the ROAR program to AN/SPS-48G standard for better reliability and usability. Operation A three-dimensional radar is mounted on a base that allows for 360 degrees of rotation. The target can be located at a given azimuth. The range of the target is also identified due to the time it takes the beam to go out and back to the receiver. What makes this radar system different is its ability to detect the height of the target ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AN/SPS-49
The AN/SPS-49 is a United States Navy two-dimensional, long range air search radar built by Raytheon that can provide contact bearing and range. It is a primary air-search radar for numerous ships in the U.S. fleet and in Spain, Poland, Taiwan aboard s, Canada on its (prior to FELEX mid-life upgrade) and New Zealand on its s. It formerly served in a complementary role aboard Aegis cruisers with the AN/SPY-1 but the systems are currently being removed during routine upgrade with no replacement. Operation First tested in 1965 aboard and introduced in 1975, the AN/SPS-49 operates in the 851–942 MHz, or L-, band and has a range of . The orange-peel parabolic shape of the antenna creates a narrow 3.3°-beam to reduce the probability of detection or jamming. It can rotate at 6 rpm in long range mode or 12 rpm in short-range mode. Default is at 12 rpm for the AN/SPS-49A(V)1, to provide more frequent scans against incoming missiles. The SPS-49A(V)1 can detect out to its full ra ...
