F-35 Armament Test Set

  • Rugged, portable tester for F-35 Lightning II Alternate Mission Equipment (AME)
  • Field and back-shop testing of launchers, pylons and subassemblies
  • Full support for MIL-STD-1760 assemblies and other JSF interfaces
  • State-of-the-art PXI architecture
  • Full parametric test with optional diagnostics


The MTS-235A is a state-of-the-art portable test set for various armament systems used on the F-35 Joint Strike Fighter including launchers, pylons, and racks. It combines the test capabilities of a Depot test set and the compact size of an I-Level test set in a rugged, flight-line qualified enclosure. The MTS-235A performs parametric functional tests on F-35 Alternate Mission Equipment (AME) components including Launchers (iARL and eARL), Pylons (Air-to-Ground and Air-to-Air) and associated subassemblies and adapters. The MTS-235A is a MIL-STD-1760 tester that supports testing of smart weapons systems.


The design of the MTS-235A is based on the proven and fielded MTS-206: Maverick Field Test Set which has been successfully deployed in 17 countries and  the MTS-209 Common Armament Test Set. The robust and modular PXI-based design of the MTS-235A provides for flexibility and upgradeability to support additional platforms and weapons systems.

The MTS-235A is controlled by a removable, integrated LCD display and touch screen - the Remote Control & Display Unit (RCDU). The RCDU allows operation of the MTS-235A from distances of up to 25 feet using an optional cable. The modular PXI chassis is secured via five shock absorbers which allows the MTS-235A to meet stringent shock and vibration requirements. Built-in heaters for the PXI chassis and the RCDU allow the MTS-235A to operate in extremely low temperatures.

The menu-driven design of the MTS-235A simplifies operation and minimizes required training and eliminates the need for cumbersome tech manuals 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-235A was designed to support additional systems and can be easily upgraded to test additional F-35 armament and avionics systems and subsystems.

Maintenance and Support

The modular design and construction of the MTS-235A provides for simplified maintenance and reduced logistics. A comprehensive Built-In-Test and system self-test provide for a complete end-to-end testing of all MTS-235A assemblies, subassemblies, cables, and adapters.

Available spare parts kits support organic maintenance using the integrated self-test adapter that provides troubleshooting to the CCA level. The high MTBF and low MTTR ensure minimal downtime and continuous trouble-free use in the harshest operational environments.


The MTS-235A 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-235A. 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 to evacuate the test set to the depot or the PMEL facility.
