The US should consider India's request (see BACKROUND below) for the Avenger - Predator C very carefully. This is because India is close to Russia in many high-tech military equipment areas, from stealth jetfighters (PAK FA) to even leasing a Russian Akula class SSN (INS Chakra).
The Pentagon or US Congress should not believe "we will not pass on technology" clauses. In terms of sensitive weapons trade and sharing India and Russia have been closer, far longer, than India and the US.
As the Avenger may develop into a vital UAV/UAS component in a future US 6th generation weapon system the risks need to be minimised that technology is secretly (or by a bit of an accident) passed to Russia.
The Russians are usually considered years behind the US in advanced UAV systems. The US Congress should not help Russia skip years of UAV development effort and costs by passing the technology to one of Russia's closest high tech "non-aligned" allies.
Also the US does not want to find that once Russia receives Avenger technology, Russian factories then turn out Russian Avengers cheaper and in export competition with the US.
Russian access to Avenger technology would also be very useful to Russia in building counter-measures against the US 6th generation fighter "herding" UAS' strategy.
Furthermore America's friends and allies (UK, Australia, Israel, East European and Middle Eastern Arab allies) don't want to be on the receiving end of airstrikes from Russian (or Iranian) built Avengers that were originally designed in America.
On June 28, 2016 The Diplomat reported on an Indian flotillas visit to the Russian Pacific Fleet Base of Vladivostok. The report also indicated:
"India and Russia already have a strong defense relationship as part of their broader strategic partnership, with both sides engaging not just in exercises and exchanges but more advanced areas like joint research, development, and production of defense technologies and systems. As an Indian government press release on the warships visit noted, varying degrees of progress on projects such as the BrahMos missile system, joint design and development of Fifth Generation Fighter Aircraft, licensed production of SU-30 aircraft and T-90 tanks, and the induction of the aircraft carrier Vikramditya into the Indian Navy are some tangible examples of this."
