The vessels each displace 1,920 long tons (1,950 t) while measuring about 95 m (311 ft 8 in) in length and 12 m (39 ft 4 in) in width. [ 1 ] [ 2 ] The OPV will use the UNIted COmbined Radio aNtenna (UNICORN) NORA-50 integration mast, which has a bar-shaped dome that houses the antennas for tactical data link, Tactical Air Navigation System ...
Naval Radio Transmitter Facility Aguada is a tall guyed radio mast erected by the United States Navy.It is used as a facility of the US Navy for ashore and U.S. and NATO ships, planes, and submarines operating at sea in areas of broadcast coverage near Aguada, Puerto Rico at by using radio waves in the very low frequency
Guyed masts are frequently used for radio masts and towers. The mast can either support radio antennas (for VHF, UHF and other microwave bands) mounted at its top, or the entire structure itself can function as a mast radiator antenna (for VLF, LF, MF). In the latter case, the mast needs to be insulated from the ground. Guyed radio masts are ...
The Phalanx CIWS (SEE-wiz) is an automated gun-based close-in weapon system to defend military watercraft automatically against incoming threats such as aircraft, missiles, and small boats. It was designed and manufactured by the General Dynamics Corporation, Pomona Division , [ 3 ] later a part of Raytheon .
The antenna must be very large at the VLF frequencies used; the supporting masts are 250–300 metres (820–980 ft) high, and the topload is about 1,900 metres (6,200 ft) in diameter. The trideco antenna was developed for high power naval transmitters, which transmit on frequencies between 15 and 30 kHz at powers up to 2 megawatts, to ...
The antenna extends to a height of 7 metres (23 ft). The system can control up to 20 firing units of guns or missiles or a combination of both. The Command and Control system features fully automatic track initiation, target tracking, target identification (IFF), target classification and designation, hovering helicopter detection threat ...
The Patrol Craft Fast (PCF), [7] also known as Swift Boat, [7] were all-aluminum, 50-foot (15 m) long, shallow-draft vessels operated by the United States Navy, initially to patrol the coastal areas and later for work in the interior waterways as part of the brown-water navy [8] to interdict Vietcong movement of arms and munitions, transport South Vietnamese forces and insert SEAL teams for ...
The central tower of each antenna system is 304 m (997.4 ft) tall. It is surrounded by six 266.7 m (875 ft) tall masts, placed on a ring with a radius of 556 m around the central tower. The remaining six towers of the array are 243.5 m (799 ft) tall, placed on a circle of 935.7 m (3,070 ft) around the central tower.
