Surface Electronic Warfare Improvement Program (SEWIP) | | | Description
The AN/SLQ-32 Electronic Warfare (EW) system, introduced in the late 1970’s, performs the mission of early detection, signal analysis, threat warning and protection from anti-ship missiles. The current SLQ-32 is deployed in 6 variants on surface ships in the fleet with the exception of LCS as well as U.S. Coast Guard cutters. The current AN/SLQ-32 is undergoing a major block upgrade.
Block 1 provides enhanced Electronic Warfare (EW) capabilities to existing and new ship combat systems to improve anti-ship missile defense, counter targeting and counter surveillance capabilities. Block 1 was focused on processor enhancement, improvements in the human machine interface of the AN/SLQ-32, Block 1A, and added a Specific Emitter Identification (SEI) receiver, Blocks 1B1 and 1B2, and High Gain High Sense receiver (HGHS), Block 1B3. The SEI and HGHS capability provides improved battlefield situational awareness. The Block 1 program is designated an ACAT II level program.
Block 2 will provide an upgraded antenna, receiver and combat system interface for the AN/SLQ-32. These upgrades are necessary in order to pace the threat and improve detection and accuracy capabilities of the AN/SLQ-32. The Block 2 program is designated an ACAT II level program.
SEWIP Block 3 is an ACAT II program that focuses on Electronic Attack (EA) capability improvements required for the AN/SLQ-32(V) system to keep pace with the threat. SEWIP Block 3 will provide a common EA capability to all surface combatants (CVN, CG, DDG, LHD) outfitted with the active variant of the AN/SLQ-32, mainly the (V)3 and (V)4, as well as CVN-78 and CVN-79 new-construction platforms. The SEWIP Block 3 Acquisition will leverage technology developed under the Office of Naval Research’s (ONR) Integrated Topside (InTop) Science and Technology (S&T) effort.
Block 4 will provide an upgraded electro-optic and infrared capabilities of the system.
| | | Features
SEWIP is an evolutionary development block upgrade program for the AN/SLQ-32 EW system installed on aircraft carrier and surface and amphibious warships (CVN, CG, DDG, FFG, LSD, LPD, LHA, LHD, and LCC) in the U.S. Navy, with total fleet-wide population of 150 systems in early 2012. The SEWIP program is made up of four block upgrades.
Block 1 provides enhanced Electronic Warfare (EW) capabilities to existing and new ship combat systems to improve anti-ship missile defense, counter targeting and counter surveillance capabilities. Block 1 was focused on processor enhancement, improvements in the human machine interface of the AN/SLQ-32, Block 1A, and added a Specific Emitter Identification (SEI) receiver, Blocks 1B1 and 1B2, and High Gain High Sense receiver (HGHS), Block 1B3. The SEI and HGHS capability provides improved battlefield situational awareness. The Block 1 program is designated an ACAT II level program.
Block 2 will provide an upgraded antenna, receiver and combat system interface for the AN/SLQ-32. These upgrades are necessary in order to pace the threat and improve detection and accuracy capabilities of the AN/SLQ-32. The Block 2 program is designated an ACAT II level program.
Block 3 will provide an upgraded electronic attack capability for AN/SLQ-32. SEWIP Block 3 will transition technology from Office of Naval Research (ONR) Integrated Topside Naval prototype. Block 3 will be designated an ACAT II level program.
| | | Background
SEWIP was established as an ACAT II program in July 2002 after cancellation of Advanced Integrated Electronic Warfare System (AIEWS). Development of SEWIP Block 1A, 1B1 and 1B2 are complete with these upgrades in full rate production and Fleet installations are in-progress. Development of SEWIP 1B3 is nearing completion. The SEWIP Block 2 contract was awarded 30 September 2009 and development is in progress. The SEWIP Block 3 program is being established. | | | Point Of Contact
