In a significant Defence advancement, the Indian Air Force (IAF) has achieved a successful test of the indigenously developed Astra Beyond Visual Range Air-to-Air (BVRAAM) missile from a Tejas fighter aircraft. This achievement marks a major milestone, as the Astra missile was launched from the Tejas Limited Series Production-7 (LSP-7) aircraft, showcasing the synergy between homegrown technologies.

The Astra missile, a product of the Defence Research and Development Organisation (DRDO), has previously undergone testing aboard a Su-30 MKI fighter. With an estimated range surpassing 100 kilometers, the Astra missile stands as a formidable indigenous creation within India's defense capabilities.

Of note, the Defence Ministry has issued an order for 248 units of the Astra Mk-1 missiles, with 200 intended for the Indian Air Force and an additional 48 earmarked for the Indian Navy.

Progress is also underway on a more advanced iteration of the Astra missile, known as the Astra Mk-II. This upgraded version garnered attention after being featured in a promotional video released by the IAF ahead of the 90th Air Force Day in the preceding year. The Astra Mk-II is anticipated to showcase enhancements such as improved jammer resistance and a domestically developed seeker. Furthermore, the missile's performance could be elevated by integrating a dual-pulse rocket motor, thereby extending its range and effectiveness.

Pioneering further strides in missile technology, India's endeavors extend to the development of the Astra Mk-III, projected to exhibit an impressive range exceeding 300 kilometers. This advanced variant will employ solid fuel-based ducted ramjet (SFDR) propulsion, marking a notable achievement in propulsion technology for long-range air-to-air missiles.

The DRDO's persistent dedication to refining SFDR technology has culminated in multiple tests, underscoring its significance in the development of extended-range air-to-air missiles.

The strategic deployment of SFDR technology paves the way for India to construct its own high-caliber long-range air-to-air missile, akin to esteemed counterparts such as MBDA's Meteor, which currently arms the IAF's Rafale aircraft fleet.

Vital to its operational efficacy, the Meteor missile relies on ramjet propulsion for enhanced maneuverability during the final stages of engagement. MBDA's technical literature expounds on the unique attributes of Meteor, detailing its thrust continuity until the point of target intercept, effectively creating a substantial No-Escape Zone, distinguishing it among air-to-air missile systems.
