In a bold step towards innovation, India’s Advanced Medium Combat Aircraft (AMCA) program is set to revolutionize its production process with 3D printing technology. By integrating 3D printing, HAL anticipates substantial benefits ranging from cost reduction and faster turnaround times to optimized material usage. The adoption of 3D printing not only promises to streamline production but also offers opportunities to mitigate material waste, a critical challenge in aerospace manufacturing.

The F-35 A design is robust; in contrast to its 8,000-hour design life, its service life has been evaluated to reach 24,000 hours. The F-35A has an extremely low radar cross-section, at 3.8mm, which reduces its radar profile. Multiple software and processor updates have been made to the F-35A. Progress includes improved weapon capability and electronic warfare systems. The current version, known as Block 3F baseline, is moving towards Block 4, with software and weapon improvements planned twice yearly in 2024.

The AMCA is currently being developed and will have sophisticated avionics, including an electronic pilot function. A fighter platform typically needs two pilots. One is a pilot who flies, while the other is a mission pilot (who directs the flying pilot). Only one cockpit and an electronic pilot will be present on this jet. As a way to improve situational awareness and collaborate with the advanced electronic warfare (EW) suite onboard the AMCA, distributed passive sensors with AI-assisted multi-sensor data fusion are anticipated.

The F-35 Lightning II features a single-seat cockpit with advanced automation and AI, enabling the pilot to handle both flying and mission-critical tasks. Its Distributed Aperture System (DAS) offers a 360-degree view, enhancing situational awareness. Supported by an advanced electronic warfare suite, the F-35’s AI-driven sensor fusion integrates data from various sensors, providing a complete battlefield picture. This technology reduces the pilot’s workload and significantly boosts the aircraft’s combat effectiveness.

since HAL realised the primary goals and advancements needed for AMCA for future aviation projects when constructing aircraft. In collaboration with international suppliers and via innovative research for newer weapons, the Defense is advancing its weaponry. The Brahmos air-to-ground missile, ASTRA, RUDRAM, Laser guided, and precision munition pods will all be made available by the AMCA. Radar and infrared search and tracking features are some additional elements that aid aircraft detection.

The F-35 features two internal weapon bays and four weapon stations. There are air-to-air missiles at the two inboard weapon stations. Among the air-to-surface weapons for the outboard station are the Joint Direct Attack Munition, the Paveway line of bombs, the Joint Standoff Weapon, and cluster munitions. The AIM-9X or AIM-132 ASRAAMs can be mounted on either of the wingtip pylons, which are canted outward to lower the radar cross-section.
