Washington: The United States was aware of India's first test-fire of an anti-satellite missile. The Pentagon has strongly denied the reports that the US spied on India's anti-satellite (ASAT) missile test by sending a reconnaissance aircraft from its base in Diego Garcia in the Indian Ocean to monitor the development. However, according to source report, the US Defense Department spokesperson Lt Col David W Eastburn told "No US assets were spying on India. In fact, the US continues to expand its enduring partnership with India, resulting in enhanced interoperability and stronger economic ties,".

Here it is to be noted that aircraft Spots, which monitors military air movements, had said that a US Air Force's reconnaissance aircraft from its base in Diego Garcia went "for a mission in the Bay of Bengal to monitor India's anti-satellite missile test". This was interpreted by many that the US spied on Indian ASAT test. Astronomer Jonathan McDowell from the prestigious Harvard-Smithsonian Center for Astrophysics told PTI on the Aircraft Spots report "I don't think that it implies coordination between India and the US,". He alleged "This implies that the US intelligence community were aware of the test in advance because to some extent they're spying on India,".

Further, He claimed "Everybody spies on their friends as well as their enemies. That's the way the world works these days. It would be surprising if the US were not detecting or observing the launch site and aware of activities preparing for the test. So one assumes that they knew it was coming,". McDowell, who is a staff member at the Chandra X-ray Center and author and editor of Jonathan's Space Report, an e-mail-distributed newsletter documenting satellite launches, said he has not looked into the issue of the aircraft, but it is certainly not surprising that the US would fly a sensor aircraft to try and observe the test.

Here it is to be noted that the Pentagon, however, strongly denied the spying allegation. Eastburn said "It's a relationship so strong that no topic is off limits,". He said "Both nations enjoy shared principles regarding our respect of sovereignty, free and fair trade, adherence to international norms, and peaceful resolution of disputes,". Air Force Space Command Commander Lt Gen David D Thompson told lawmakers Thursday that the US was aware that India's ASAT test was coming.

Thompson said "First of all, it was detected, characterised and reported by Air Force Missile Warning systems and Airmen at Buckley AFB. Immediately after the test (it struck the target vehicle), the Joint Space Ops Center and USAF 18 Space control Squadron began collecting information about the breakup of the vehicle,". "First of all, we knew it was coming because of flight bans that India had announced and information they published previously. The launch occurred at 1.39 AM EST," he told members of the powerful Senate Armed Services Subcommittee on Strategic Forces during a Congressional hearing.

Prime Minister Narendra Modi had on Wednesday announced that India successfully test-fired an anti-satellite missile by shooting down a live satellite, describing it as a rare achievement that puts the country in an exclusive club of space super powers. The test made India the fourth country in the world after the US, Russia and China to acquire the strategic capability to shoot down enemy satellites.
