Contractor: Hughes Missile Systems Co., Tucson, Ariz. Power Plant: Cruise turbo-fan engine; solid-fuel booster Antenna: Array of 6 dipoles @ 150 Mhz VHF Length: 18 feet 3 inches (5.56 meters); with booster: 20 feet 6 inches (6.25 meters) Height of 6 meters Weight: 2,650 pounds (1192.5 kg); 3,200 pounds (1440 kg) with booster, 3800 pounds in capsule Diameter of 6 to 12 inches CM Radar Picket Diameter: 20.4 inches (51.81 cm) This section 4 to 6 meters Wing Span: 8 feet 9 inches (2.67 meters) 20ft Range: Land attack, conventional warhead: 600 nautical miles (690 statute miles, 1104 km) Water Surface Speed: Subsonic - about 550 mph (880 km/h) Guidance System: Inertial, TERCOM, and GPS Antenna covers 360° (omni-azimuth). Therefore, no angle info from a single sensor. Warheads: Conventional: 1,000 pounds Bullpup, or Conventional submunitions dispenser with combined effect bomblets, or WDU-36 warhead w/ PBXN-107 explosive & FMU148 fuze Plays as: Regular Thawk with characteristics noted above; launched from standalone capsule vice platform. Electronics However, range and Doppler info on a target can be ascertained through an appropriate spacing of multiple sensors in a barrier configuration. The normal spacing between sensors would be 2 km, resulting in 1.5 sensors per kilometer of barrier length. Barrier Geometry 21” !

Size of total package: 4ft x 4 ft x 20 ft; 20,000 lbs (See Bunker Estimation Technique, previous slide). Probe Pulse Tactical Acoutics Measurement and Decision Aid (TAMDA) Note: These units are assumed to be able to communicate directly with undersea sensor nets (IUSS, ADS, and DADS). Plays as: Torpedo Launch from point in space, vice submarine or surface platform. Ref: FAS Web Site 99-NUWC/0594U.M6 TAMDA (surface, roughly sonobuoy size) provides, via a combination of probes, acoustic projections, and receivers acoustic environmental information on Bottom Reflection Loss, Reverberation, Bottom Depth, Bottom Type, Bottom Scattering Strength, sound velocity profile and ambient noise monitoring. BT Sensor 0160-JR Float Transceiver Elements TAMDA or a similar environmental monitoring system will be necessary to plan and place bottom acoustic sensors effectively in the real world. An active source LF Xmitter will also be necessary to mount an effective acoustic ASW campaign against modern SSs. Anchor 14 December 2000 Sea Lance LFAS (bottom, roughly 21” dia and 10 ft long in capsule), acting in conjunction with other receiver sources or LFAS units, can act as an illuminator and receiver for multi-static targeting. It can also provide limited insitu environmental data, particularly direct measurement of propagation loss. For Loop 3; TAMDA is assumed to be employed as a data-gathering device prior to the planning and placement of any acoustic fields. LFAS is presumed to be placed with each 100x100nmi DADS array, four to a field. 15 Total Ship Systems Engineering Team 2000 Notional Adversary ! ! ! ! !

In the team’s opinion, the design has fulfilled all of the requirements set forth by the sponsor and as specified in the requirements document. We have completed a loop around the design circle and in some specific instances several iterations have been made. The combatant could fill some essential gaps in the current fleet and is a cheap, flexible and capable alternative to large CRUDES ships. The tow is a viable option which needs further physical and computational experiments to validate its utilization. 14 December 2000 Sea Lance 109 Total Ship Systems Engineering Team 2000 Risk Assessment ! ! ! ! ! The tow is at risk mostly due to lack of good data to thoroughly evaluate the alternative. The AWJ-21 is currently in the design phase at Bird-Johnson Some catamaran data was extrapolated from commercial designs Validate the assumption that wave-piercer and ride stabilization system will reduce accelerations Human Factors 14 December 2000 Sea Lance 110 Total Ship Systems Engineering Team 2000 Recommendations ! ! ! ! !
