Mission Readiness Test Set (MRTS)

Also known as
  • MRTS
  • Lockheed Martin MRTS

Lockheed Martin's Mission Readiness Test Set (MRTS) is a portable, standalone Windows tester for Paveway II laser-guided bomb guidance assemblies and related smart-munition guidance units. The company says it performs nine go/no-go checks, weighs under 60 pounds, and supports O-, I-, and D-level maintenance while replacing older TTU-594A/E test sets.

Test Coverage And Maintenance

Lockheed Martin says MRTS provides laser functional mission readiness testing for Paveway II LGB computer control group guidance assemblies, plus Paragon direct attack munition and Dual Mode LGB Weapon Guidance Units.

Measured factValue
Go/No-Go functionsNine, including self-test, code correlation/missing pulse logic, inter pulse stability, long and short last pulse logic, pulse width discrimination, squib fire delay, steering/tracking accuracy, voltage/continuity, and multi/dual laser.
Maintenance levelsSupports O-, I-, and D-level maintenance activities.
Legacy equipmentReplaces TTU-594A/E and is an affordable alternative to TTU-595 test sets.

Lockheed Martin describes MRTS as lightweight, easy to set up, and Windows-based.

Paragon direct attack munition, Dual-mode laser-guided bomb, MunitionsMunitionsParagon direct attack munitionDual-mode laser-guided bombParagon is Lockheed Martin's branded Dual Mode Plus laser-guided bomb, a GPS/INS and semi-active-laser direct-attack munition tested from the F/A-18E/F Super Hornet and introduced under the Paragon name in 2017. Specialist designation references identify the 500 lb-class all-up weapon as GBU-73/B and the Paragon guidance section as WGU-53A/B, while Lockheed Martin support-equipment literature ties the munition to PMTS training emulation and MRTS mission-readiness testing rather than documented combat employment.

It gives aircraft a non-emitting air-to-air detection and tracking channel, has supported F-15C missile-cue testing with AIM-9X and AIM-120 shots, and moved into Navy IRST Block II fielding for the Super Hornet in 2025.

Raytheon traces production to 1968, while later Raytheon, Lockheed Martin, and Raytheon UK lines cover Paveway II, Paveway III, dual-mode Enhanced Paveway, Paveway IV, and Paveway II Plus kits documented in combat-use and transfer records from the Falklands and Gulf War through Afghanistan, Iraq, Libya, Ukraine, and Yemen.
