The full-scale engineering development efforts of India's Tejas Mk2 multi-role combat aircraft (MRCA) recently took a significant step forward when the Bangalore-based Aeronautical Development Agency (ADA), in consultation with the Indian Air Force (IAF), froze the MRCA's design, which will now have a length of 14.2 metres (1-metre more than that of the Tejas Mk1 for incorporationg a stretched nose section and a modified fuselage section aft of the cockpit for housing an expanded complement of mission avionics LRUs), height of 4.6 metres (as opposed to 4.4 metres of the Tejas Mk1) to accommodate an enlarged vertical tail-section, and a wingspan of 8.2 metres—same as that of the Tejas Mk1—that, however, will feature an increased wing area. External stores capacity will be boosted to 5,700kg (as opposed to 3,500kg for the Tejas Mk1), while the twin internal air-intake ducts will be minimally enlarged to cater to the increased airflow requirements of the 98kN thrust F414-GE-INS6 turbofan built by GE Aero Engines.
The Ministry of Defence had, last January, sanctioned US$542.44 million (Rs2,431.55-crore) for ADA to develop the IAF's Tejas Mk2 variant and the Indian Navy's LCA Mk2 (Navy) variant so that the first Tejas Mk2 prototype can take to the skies by September 2013 and make this prototype fly by December 2014, following which the MoD-owned Hindustan Aeronautics Ltd (HAL) would begin series-producing the MRCA by 2016. While the IAF is committed to procuring an initial 83 Tejas Mk2s, the Navy has expressed its firm requirement for 46 LCA Mk2 (Navy). Just like the Tejas Mk1, the airframe of the Tejas Mk2 will incorporate 13 major composites-built structures fabricated by TATA Advanced Materials Ltd (TAML), which was awarded the contract after the state-owned National Aerospace Laboratory (NAL) expressed its failure to deliver the structures on time. Structures to be produced by TAML for each aircraft will include a rudder assembly, fin assembly, 60 carbon-fibre reinforced (CFC) wing spars, 38 wing fuselage fairing skins, 20 wing fuselage fairing blocks, 41 CFC centre fuselage components, two forward undercarriage doors and two aft undercarriage doors.
