The principal improvements are in the Advanced Tomahawk Weapon Control System (ATWCS) fire-control system, and the TC2S software. The fielded Baseline III Tomahawk Weapon System continues to receive incremental upgrades. Block III was first used in the September 1995 Bosnia strike (Deliberate Force) and a year later in the Iraq strike (Desert Strike). The WDU-36 uses a new warhead material based upon prior China Lake warhead technology investigations, PBXN-107 explosive, the FMU-148 fuze (developed and qualified for this application), and the BBU-47 fuze booster (developed and qualified using the new PBXN-7 explosive). China Lake designed, developed, and qualified the WDU-36 warhead in 48 months to meet evolving Tomahawk requirements of insensitive munitions ordnance compliance and range enhancement, while maintaining or enhancing ordnance effectiveness. With GPS, TLAM route planning is not constrained by terrain features, and mission planning time is reduced.
#TACTICAL TOMAHAWK UPGRADE#
The Tomahawk TLAM Block III system upgrade incorporated jam-resistant Global Positioning System (GPS) system receivers provided a smaller, lighter warhead, extended range, Time of Arrival, and improved accuracy for low contrast matching of Digital Scene Matching Area Correlator. It has added global positioning system guidance and redesigned the warhead and engine in the missile's block III configuration that entered service in March 1993. Tomahawk Block III Since the Gulf War, the Navy has improved its Tomahawk missile's operational responsiveness, target penetration, range, and accuracy.
#TACTICAL TOMAHAWK FULL#
Full end to end testing is completed with every mission. The testing emphasized operationally realistic test scenarios, including battle group operations, for missiles launched from TOMAHAWK capable Block II and Block III surface ships and submarines. The program tested approximately eight missiles each year, two TLAM/N and six TLAM/C and D missiles. The objective of the program was to verify, in a statistically significant manner, that missile performance, accuracy, and reliability met operational requirements and thresholds. The testing ranĬoncurrently with the Operational Test Launch (OTL) program. The TOMAHAWK missile performance testing was an ongoing, five year study of TLAM performance which began in 1995. Both conventional variants (TLAM/C and D) were tested and determined to be operationally effective and operationally suitable, with full fleet introduction recommended. The testing was performed on both surface and subsurface units under various environmental conditions, continuing through July 1994. The Blk III was the first time GPS was used to aid missile guidance. In October of 1990, the OPEVAL of the Blk III missile began. Some of these improvements included a TASM improved sea skimming variant, an improved booster rocket, cruise missile radar altimeter, and the Digital Scene Matching Area Corellator (DSMAC) Blk II. BLK II improvements were made and tested with all variants in July 1987 through September 1987. The missile was determined to be potentially operationally effective and potentially operationally suitable, with limited fleet introduction recommended.Īs missile improvements were made, follow on test and evaluation continued. In April of 1988 the OPEVAL of the conventional land attack submunitions missile (TLAM/D) was tested. In all phases, the AUR was determined to be potentially operationally effective and potentially operationally suitable, and full rate production was recommended. The ship launched variants were tested from December 1983 to March 1985. The last three phases tested the ship launched variants. The sub launched antiship version (TASM), conventional land attack missile (TLAM/C), and nuclear land attack variant (TLAM/A) were tested from January 1981 to October 1983. The first three phases all involved testing of the submarine launched TOMAHAWK missiles.
Operational evaluation to support a milestone III full rate production decision on the TOMAHAWK missile began in January 1981. The missile is delivered to ships and submarines as an all-up-round (AUR), which includes the missile that flies the mission, the booster that starts its flight, and the container (canister for ships and capsule for submarines) that protects it during transportation, storage and stowage, and acts as a launch tube. The missile concept is one of a wooden round.
Both are identical in appearance, but different in capabilities. These two variants of Tomahawk cruise missile are distinguished by their warhead TLAM-C has a conventional unitary warhead, and TLAM-D has a conventional submunitions (dispense bomblets) warhead. The Tomahawk is a mature missile weapons system with Block II and III, C (unitary warhead) and D (bomblet dispersion) versions in fleet use.
