MTS-209 Selected to Support Thailand T-50 Trainer Aircraft

Common Armament Test Set Offers Comprehensive I-Level Test Capabilities for T-50 Aircraft

Irvine, CA. January 9, 2017 – Marvin Test Solutions’ MTS-209 Common Armament Test Set has been selected by Korea Aerospace Industries (KAI) as part of the support package for a group of T-50TH aircraft purchased by the Thai Air Force in 2015 and slated for delivery in the next 24 months. The new aircraft will replace aging L-39 Albatros trainers.

The T-50 “Golden Eagle” was jointly developed by KAI and Lockheed Martin as a multi-role trainer and has several variants, including a light combat aircraft, capable of supersonic speeds.

The MTS-209 (also referred-to as the Stores Suspension Unit Tester, or SSUT) is a state-of-the-art portable test set for various armament systems used on the F-16, F-15, F-18, T-50, TA-50, FA-50, Hawk and additional aircraft, supporting a wide range of Alternate Mission Equipment (AME) including missile launchers, aircraft pylons, and bomb racks. Based on the proven MTS-207 Rugged Field Test, the MTS-209 combines the test capabilities of an I-Level (backshop) test set in a compact, rugged, flightline-qualified enclosure. The test set’s modular design simplifies logistics, and its flexible, scalable PXI architecture enables future upgradeability to match evolving test requirements.

Common Armament Test Set

  • A rugged, portable common armament systems tester for F-16, F-15, TA-50, FA-50 and other platforms
  • Field and I-level (back-shop) test capabilities
  • Supports a wide complement of Alternate Mission Equipment (AME) including launchers, bomb racks, ejector racks, and pylons
  • State-of-the-art modular PXI architecture
  • Full parametric test with built-in diagnostics


The MTS-209 is a state-of-the-art portable test set for various armament systems used on the F-16, F-15, F-18, TA-50, FA-50 and additional aircraft. The MTS-209 supports a wide range of Alternate Mission Equipment (AME) including launchers, pylons, and racks. It combines the test capabilities of an I-Level test set in a compact, rugged, flight-line qualified enclosure. The MTS-209 performs parametric functional tests on AME components including Launchers (LAU-117, 16S210, LAU-127,, LAU-128, LAU-129, LAU-7,etc.), bomb racks (MAU-12, MAU-50, SUU-20, TER-9, etc.), Remote Interface Units (RIUs) and Pylons. The MTS-209 can also test MIL-STD-1760 aircraft stations and weapon systems.


The core design of the MTS-209 is based on the proven and fielded MTS-207: Rugged Field Test Set which has been successfully deployed worldwide. The robust and modular PXI-based design of the MTS-209 provides for upgradeability to support additional platforms and weapons systems.

The MTS-209 is controlled by a removable integrated LCD display and touch screen — the Remote Control & Display Unit (RCDU) or via a ruggedized laptop or tablet. The RCDU / laptop / tablet allow operation of the MTS-209 from distances of up to 25 feet using a menu-driven, graphical user interface (GUI). The modular PXI chassis is secured via five shock absorbers which allows the MTS-209 to meet stringent shock and vibration requirements. Built-in heaters for the PXI chassis and the RCDU allow the MTS-209 to operate in extremely low temperatures.

Online cable identification

The menu-driven design of the MTS-209 simplifies operation and minimizes required training and cumbersome tech manual use during operation. A menu-driven structure, developed using ATEasy, guides the user and creates an operational environment that virtually eliminates operator errors. Cable detection is automatic and, in the event of a misconnection, clear prompts instruct the user as to which cables are required and how to identify and connect them.

Future Growth

The MTS-209 was designed to support many additional weapons systems and platforms and can be easily upgraded to test similar armament systems on additional platforms such as A-10, F-22, F-35, and F-18. MTS-209 variants such as the MTS-206, MTS-207, AN/TSM-205B, and the MTS-235 are already being used on The F-35, MC-130, and the Maverick and Hellfire missile systems (platform independent).

Maintenance and Support

The modular design and construction of the MTS-209 provides for simplified maintenance and reduced logistics. A comprehensive self-test program utilizes a self-test adapter to perform a complete test of all MTS-209 hardware including Circuit Card Assemblies (CCAs) and cables and provides troubleshooting to the faulty assembly. Using an available spare parts kits, customers can organically support the MTS-209 by replacing CCAs and cables according to self-test troubleshooting data. The high MTBF and low MTTR ensure minimal downtime and continuous trouble-free use in the harshest operational environments.



The MTS-209 employs an innovative calibration technique that further simplifies maintenance and reduces scheduled maintenance down-time. Multiple NIST-traceable high-precision references have been incorporated into the design of the MTS-209. The test set verifies its calibration status against these references every time the self-test is performed and in the event the test set is out of calibration, the user is instructed to initiate an automated calibration procedure that calibrates the test set measurement and stimuli devices against the built-in references. The references have to be checked once every 2 years using standard PMEL equipment that can be brought to the field, eliminating the need for evacuation of the test set to the depot or the PMEL facility.

User-Defined Programs

The unique software architecture of the MTS-209 allows customers to add their own custom test programs for AME not supported by the MTS-209. This innovative architecture allows customers to do so without compromising the integrity of all standard MTS-209 test programs.
