New Antares engine, contract signed: http://www.defencetalk.com/russian-firm-seals-1-billion-deal-to-supply-us-rocket-engines-62019/
It's official, thank God, I thought the Congress may have scared few guys buying russian engines but I was wrong. -

Why is there a contract being signed with Energia? It is NPO Energomash who is producing the engines - or are they owned by Energia? -

Looks like this needs a change of thread title to RD-181.

RSC "Energia" through its subsidiary ZEM RKK "Energy" became the owner of 13.98% of the shares of NGOs "Energomash" - the leading Russian manufacturer of liquid rocket engines (the remaining shares of the company - owned by the state).

Quote from: Peter B. de Selding @pbdes
Orbital Sciences: 'If/when US alternative available, we'll consider it for Antares. Till then, the RD-181 is the only viable engine option.'
Quote from: Peter B. de Selding @pbdesOrbital: Russian estimates of $1B for our RD-181 contract include all options that are way beyond our commitment, & rounds up value too.
I dunno, feels weak. If Orbital really wants to refute the $1B number, I think they're going to have to make the actual price per engine public. -

The only people they have to refute it to is customers. And that won't be public. -

Earlier someone at Orbital claimed it was nowhere near $1B. When the only source was some article in Russian press I was inclined to believe them. But now it seems like the full contract is worth pretty close to $1B, and Orbital is making sort of weak attempts to minimize it.
Nobody wants to be the company that just "sent a billion dollars to Russia."
I don't think Orbital could have done things any better. I just wish they'd either say "Yeah the engines cost [$16M] each" or if the numbers are so secret they should just say "no comment" and have a better NDA with their supplier in the first place. -

$16 million is nice number when you divide One Billion by 60.
But is it really $16 or is it lower than $16 for each engine. Do other program expenses exist in the contract? Maybe the per unit cost is lower, while there are other engineering costs, support costs, and options for other engineering work and upgrades that bring it to one billion?
Dividing total program costs by the number of units produced is how you end up in a death spiral. Of course that may imply that if they only buy 20 engines the price tag with "overhead" will be well north of $16 million...
Edit: Also, what rubble conversion rate did they use? -

Wooo boy. Well I am glad they settled on something but disappointed they went with another Russian motor. Still think they would have been better off going to Blue Origin or a similar concern for a new motor. Would have been more expensive in the short term but something tells me they may live to regret not doing it in the long term.New Antares engine, contract signed: http://www.defencetalk.com/russian-firm-seals-1-billion-deal-to-supply-us-rocket-engines-62019/

Engines start arriving this summer. No other company could do that.
RD-180 or RD-181 was only way to save Antares. -

Title needs to be changed as RD-193 is an ungimballed LRE intended only for Soyuz 2.1v, whereas gimballing RD-181 is direct export version of RD-191 NOT RD-193 which is intended for Antares and other foreign rockets.

Партия двигателей РД-181 передана заказчику
В НПО #Энергомаш представителями американской компании Orbital Sciences Corporation были подписаны формуляры на очередную партию из четырех товарных двигателей РД-181.
В течение трех дней до передачи двигателей представители компании-заказчика проводили их внешний осмотр, проверку запасных частей, инструментов и принадлежностей, а также сопроводительной документации. Данная приемка #РД181 является второй в 2019 году. В ближайшее время двигатели будут подготовлены и отправлены компании-заказчику.
Жидкостный ракетный двигатель РД-181 разработан и производится АО "НПО Энергомаш" в рамках заключенного в декабре 2014 года контракта с компанией Orbital Sciences Corporation. Двигатель предназначен для установки на американские ракеты-носители Antares.
