Early suspension of US reliance on the Russian RD-180 rocket engines to deliver heavy payloads into space will cost US taxpayers as much as $5 billion, Air Force Secretary Deborah Lee James told the Senate Armed Services Committee on Thursday.

In 2014, the US Congress passed a law demanding the United States phase out its reliance on the Russian-made RD-180 rocket engines it uses to launch national security and other heavy payloads to space.

The law called for a shift to competitive, US-made rocket engines. The United Launch Alliance and Aerojet Rocketdyne were the confirmed recipients of Air Force contracts to build the RD-180 replacement.

"That approach [using a new engine] would cost additional dollars to the Air Force budget to the taxpayer anywhere on the order of $1.5 billion more to maybe as high as $5 billion more, depending on when you would cut off the RD-180 and start this approach," James stated.

In the two years after implementing a purchasing ban on the RD-180, the US Congress has been forced to lift that ban to ensure its access to space on the Atlas V rocket, powered by the Russian rocket engine.

Furious McCain: Pentagon Can't Overcome Its Russian Engines Addiction
Despite John McCain's profound displeasure, US defense officials are not inclined to abandon the RD-180 Russian rocket engines until 2021 or 2022 earliest.

Since the collapse of the Soviet Union the United States Air Force has become one of Russia's longstanding customers: for years the Pentagon was buying the RD-180 Russian rocket engines to put its satellites into space.

However, after the Washington-fomented February coup in Ukraine in 2014, the Russo-American relationship has deteriorated.

The Pentagon has faced the painful dilemma of whether or not to abandon the RD-180, a cost-effective booster engine with unique features, which powers the Atlas 5 rocket built by United Launch Alliance, a joint venture of Lockheed Martin Corp and Boeing Co.

Sen. John McCain, the chairman of the Senate Armed Services Committee, believes that the US Air Force should stop buying Russian rocket-engines as soon as possible.

In order to overcome the US Air Force's Russian engines "addiction," Senator McCain and Majority Leader Rep. Kevin McCarthy have proposed legislation which would ban the import of the NPO Energomash RD-180 engines by 2019.

"It is morally outrageous and strategically foolish to ask American taxpayers to subsidize Russia's military industrial base," McCain said in an official statement, referring, predictably, to Russia's non-existent invasion of Ukraine and Moscow's imaginary threat to Europe.

"Our policies should facilitate a competitive environment that provides the incentive to scale each component required to access space. This was achieved in the fiscal year 2016 National Defense Authorization Act that was signed into law. But in a last minute maneuver, a provision was tucked into an unrelated spending bill that provides an indefinite lifeline to Russian rocket engines to power American space launches," McCarthy told the Senate Armed Services Committee.

It is turn the Air Force says that it has no alternative but to use the Russian engines, Dave Majumdar, the Defense Editor of The National Interest, notes in his article.

The service argues that "it is required by law to provide short access to space using commercial services," the journalist points out, explaining that the Pentagon needs eighteen RD-180s "on hand at any time" for its heavy lifters. Whether one likes it or not, right now there is no viable alternative to the RD-180 booster engines.

"We must keep in mind the only launch vehicles that can reach the full range of orbit and carry our heaviest payloads today, remain the Atlas and Delta families," Air Force secretary Deborah Lee James told the Senate Armed Services Committee, as quoted by Majumdar.

Robert Orton Work, the current United States Deputy Secretary of Defense, said in an official statement on Wednesday that the Pentagon regards public-private partnerships as a way to suspend the reliance on Russian boosters. The initiative is expected to be kicked off in fiscal 2017.

However, Work added that it is not until 2021 or 2022 that the Pentagon will stop using the Russian-made engines.
