AN/SPS-49 is a long-range, two-dimensional air search radar used by the United States Navy and other navies, including the Royal Australian Navy, Royal Canadian Navy, and Japanese Maritime Self-Defense Force. The AN/SPS-49 is designed to detect and track aircraft, missiles, and other airborne targets at long range, providing early warning and cueing for surface-to-air missile systems such as the Aegis Combat System and Phalanx CIWS. The radar is also used on amphibious assault ships, cruisers, and destroyers of the United States Navy, including the Ticonderoga-class cruiser and Arleigh Burke-class destroyer. The AN/SPS-49 has been used in various military operations, including the Gulf War and Operation Enduring Freedom, in conjunction with other radar systems such as the AN/SPY-1 and AN/SPS-67.
● Introduction
The AN/SPS-49 is a high-power, L-band radar system that uses a parabolic antenna to transmit and receive radar signals. The radar is designed to provide long-range detection and tracking of airborne targets, including fighter aircraft, bombers, and cruise missiles. The AN/SPS-49 is often used in conjunction with other radar systems, such as the AN/SPS-48 and AN/SPS-67, to provide a comprehensive air picture for naval task forces. The radar has been used by various navies, including the United States Navy, Royal Navy, and French Navy, on a range of ships, including aircraft carriers, cruisers, and destroyers, such as the Nimitz-class aircraft carrier and Charles de Gaulle (R91).
● Design_and_Development
The AN/SPS-49 was developed in the 1970s by Lockheed Martin and ITT Corporation, with the first production units delivered to the United States Navy in the early 1980s. The radar system was designed to replace the earlier AN/SPS-37 and AN/SPS-43 radar systems, which had limited range and resolution. The AN/SPS-49 uses a high-power klystron transmitter and a low-noise amplifier receiver to achieve long-range detection and tracking of airborne targets. The radar system has undergone several upgrades and modifications over the years, including the introduction of new signal processing algorithms and antenna designs, such as the phased array antenna used on the Aegis Combat System. The AN/SPS-49 has been integrated with other systems, such as the Link 11 and Link 16 data links, to provide a network-centric capability for naval task forces, including the United States Fifth Fleet and United States Seventh Fleet.
● Operational_History
The AN/SPS-49 has been used in various military operations, including the Gulf War, Operation Enduring Freedom, and Operation Iraqi Freedom. The radar system has been used on a range of ships, including cruisers, destroyers, and amphibious assault ships, such as the USS Princeton (CG-59) and USS Wasp (LHD-1). The AN/SPS-49 has also been used by other navies, including the Royal Australian Navy and Royal Canadian Navy, on ships such as the HMAS Adelaide (L01) and HMCS Iroquois (DDH 280). The radar system has been used in conjunction with other radar systems, such as the AN/SPY-1 and AN/SPS-67, to provide a comprehensive air picture for naval task forces, including the United States Pacific Fleet and United States Naval Forces Central Command.
● Technical_Characteristics
The AN/SPS-49 is a high-power, L-band radar system that operates at a frequency of 1-2 gigahertz. The radar system uses a parabolic antenna with a diameter of 12-15 feet (3.6-4.5 meters) to transmit and receive radar signals. The AN/SPS-49 has a maximum range of over 200 nautical miles (370 kilometers) and can detect targets at altitudes of up to 100,000 feet (30,000 meters). The radar system uses pulse-Doppler signal processing to detect and track airborne targets, and can track multiple targets simultaneously, including aircraft, missiles, and unmanned aerial vehicles.
● Variants_and_Upgrades
There have been several variants and upgrades of the AN/SPS-49 over the years, including the AN/SPS-49(V)1, AN/SPS-49(V)2, and AN/SPS-49(V)5. The AN/SPS-49(V)1 is an upgraded version of the original AN/SPS-49, with improved signal processing and antenna designs. The AN/SPS-49(V)2 is a variant of the AN/SPS-49(V)1, with additional capabilities such as air traffic control and surface surveillance. The AN/SPS-49(V)5 is a modernized version of the AN/SPS-49, with improved electronics and software.
● Operators
The AN/SPS-49 is used by several navies around the world, including the United States Navy, Royal Australian Navy, Royal Canadian Navy, and Japanese Maritime Self-Defense Force. The radar system is also used on ships of the French Navy, German Navy, and Italian Navy, such as the Charles de Gaulle (R91), Sachsen-class frigate, and Giuseppe Garibaldi (C 551). The AN/SPS-49 has been integrated with other systems, such as the Aegis Combat System and Phalanx CIWS, to provide a comprehensive air defense capability for naval task forces, including the United States Sixth Fleet and United States Seventh Fleet. The AN/SPS-49 is also used by other organizations, such as the United States Coast Guard and National Oceanic and Atmospheric Administration, on ships such as the USCGC Bertholf (WMSL-750) and NOAA Ship Ronald H. Brown (R 104).
