A new Aeronautical Development Agency tender linked to the LCA Mk2’s first prototype provides another indication of the fighter’s progression toward detailed systems integration and future testing.The requirement focuses on automated testing of the aircraft’s electrical cable harnesses. The tender, listed under GEM/2026/B/7909097, concerns Prototype Vehicle 1 and calls for an approximately five-month work package.Aircraft wiring plays a critical role in connecting the many electronic and electrical systems required for modern fighter operations. Flight computers, sensors, communications equipment, avionics modules, power systems, and mission equipment all depend on reliable electrical connections.As the LCA Mk2 contains a complex network of such connections, automated verification can provide engineers with a systematic method of checking the aircraft’s wiring before power is applied.The testing process can identify problems involving continuity, insulation, connectivity, and other electrical parameters. Early detection is valuable because correcting a wiring problem becomes considerably more difficult when cables and components are already installed deep inside an assembled aircraft.The timing of the activity is also noteworthy. PVI is the first prototype intended to support the flight-test phase of the Mk2 programme. Electrical validation is therefore one of the necessary steps between physical assembly and full aircraft systems testing.The LCA Mk2 is being developed as a larger medium-weight multirole fighter compared with the Tejas Mk1 family. Its design incorporates increased fuel capacity, higher payload potential, and a more extensive electronic and avionics suite.Power will come from the General Electric F414 engine, which provides a higher thrust class than the F404 used by current Tejas variants.For a prototype of this complexity, electrical-system verification is a crucial part of development. A fault in a wiring harness can affect multiple systems and potentially create delays if discovered only after the aircraft reaches advanced testing stages.Automated testing provides a way to establish confidence in the electrical architecture before the aircraft’s systems are progressively energized. It can also reduce the time required to locate faults during later integration work.The latest tender forms part of a broader series of activities surrounding the Mk2 prototype. HAL continues work on manufacturing and assembly, while ADA is supporting the programme through contracts covering specialized equipment and integration requirements.These individual activities may appear routine when considered separately, but together they show the aircraft moving through successive development stages. The programme is gradually transitioning from structural construction toward complete system integration.The harness-testing effort will therefore contribute to the groundwork required for future power-on checks, ground trials, and eventually flight testing of the LCA Mk2 prototype.
