ЦитироватьBoeing-Lockheed venture raises SpaceX explosion in fight over Pentagon contract    
By Christian Davenport September 21 at 8:49 PM
 
The recent explosion of a SpaceX rocket should raise concerns about going with the lowest bidder on sensitive national security launch contracts, the chief executive of the United Launch Alliance wrote in a letter to top Pentagon officials earlier this month.
Tory Bruno, ULA's chief executive, urged the Air Force to postpone the deadline for bids, saying it should take time to explore the impact of SpaceX's rocket failure while also taking into account both companies' experience and past performance.
The Pentagon should have particular reservations, Bruno wrote, given that two of SpaceX's Falcon 9 rockets have blown up, which he said "serve as a reminder of the complexity and hazards intrinsic to space launch services."
"This strategy defies both law and logic and puts hundreds of millions of taxpayer dollars and Warfighter mission needs unnecessarily at risk," he wrote.
The letter, a copy of which was obtained by The Washington Post, is the latest salvo in one of Washington's most contentious contractor feuds, one that has pitted a pair of the world's most powerful defense contractors against a brash billionaire looking to shake up a calcified market by offering launches for far less money. And it's the most glaring example yet of a competitor going after SpaceX for the two explosions.

The Air Force did not immediately respond to requests for comment. SpaceX declined to comment.
For a decade, ULA, the joint venture between Lockheed Martin and Boeing, had a monopoly on launching national security satellites for the Pentagon. But then SpaceX, the hard-charging company founded by tech entrepreneur Elon Musk, sued the Air Force for the right to compete, saying it could save taxpayers millions of dollars. The parties settled, and last year the Air Force granted SpaceX the certification to compete, saying it had met its rigorous technical standards.
ULA fired its chief executive and hired Bruno, who vowed to "literally transform the company" for it to compete against SpaceX, which had already won contracts from NASA to fly cargo and eventually astronauts to the International Space Station.
But faced with competition for the first time, ULA declined to bid on the first of the contested contracts last year, saying, among other things, that the Air Force was giving too much weight to the price companies bid.
The emphasis on price — and not experience and past performance — put ULA at a disadvantage, the company said.
SpaceX then walked away with the $82.7 million contract, the first of nine launches to be competitively bid, at a price far less than the Air Force had been paying ULA. Lt. Gen. Samuel Greaves cheered the service's new partner, saying in a statement last month that the Air Force hopes "to continue fostering competition in order to promote innovation and reduce cost to the taxpayer while maintaining our laser focus on mission success."
But two of SpaceX's rockets have exploded in spectacular fireballs, raising concerns about their reliability and safety. One of its rockets blew up last year while carrying $118 million worth of cargo to the space station. Earlier this month, a rocket blew up during fueling before an engine test and a $195 million satellite was destroyed.
The Air Force is part of the investigation into the most recent failure, but officials have said the explosion has not affected SpaceX's certification.
In his letter to Air Force Secretary Deborah Lee James and Frank Kendall, the Pentagon's chef weapons buyer, Bruno sought to contrast his company's long record of accomplishment with its relatively new competitor. He trumpeted ULA's 111 consecutive successful launches on its Atlas and Delta rockets. And he wrote that the company has a long heritage of delivering "into precise orbits some of the most sensitive and valuable national security payloads directly supporting our country's Warfighters — and it has done so with unprecedented dependability and mission success."
Focusing so heavily on price is only appropriate when the "risk of unsuccessful contract performance is minimal," he wrote. And the recent SpaceX explosion "reminds us that the risk associated with space launch service contracts is well beyond 'minimal.' "
The criteria used by the Air Force in the contract to launch its GPS III satellite "relegates technical performance to an afterthought, favoring price as the determining evaluation factor — a purchasing strategy befitting perhaps of basic commodity contracting services, not the 'incredible challenge' of spaceflight."
Bruno urged the Air Force to push back the deadline for bids by 60­ days so that it could "explore the nature and impact" of SpaceX's failure and also ensure that it "adequately factors" criteria such as "reliability, schedule certainty and past performance." And he hinted that the fight may not be over, saying ULA's concerns "could conceivably be litigated in a courtroom."
Despite the plea, the Air Force proceeded with the bids, which were due Monday. This time, ULA said it submitted a bid.

ЦитироватьDecatur was sized for 40 Delta's per year.
The content of those 40 was also intended to be > 60% buy, meaning that less than 40% of the 40 rocket's content was to be manufactured in Decatur with the rest in the supply chain.
Decatur has around twice the square footage as Hawthorn
So, yeah... its a lot less crowded.
This will be helpful as we overlap Atlas, Delta-Heavy and Vulcan during the transition.
It is also enabling our effort to bring content and suppliers inside our walls. For example, RUAG is now occupying space inside Decatur to build our composite structures (bringing jobs from overseas to the US, BTW)

ЦитироватьYes. We have giant bridge mills in Decatur that mill the isogrid into aluminum plates.
These are then "bump pressed" into the tank's radius on massive hydraulic break presses. 4 of these are welded together to form the propellant tanks.
We also have North America's largest chemical treatment facility within Decatur's walls.
ЦитироватьHonestly, the original price for our base Rocket (AtlasV 401) was more like $184M. Much, much lower now. On its way to sub $100M
ЦитироватьYes. The first day of the block buy, it was $184M. In the block buy, ULA committed to an average price across all in that buy of $164. Which means that they would be less than $164M by the end in order to average out to the target.

ЦитироватьMighty Atlas‏@Rocket_AtlasV
@torybruno Ah. since AR-1 produces significantly less thrust than RD-180 would a solution be dual engine or more SRBs?
Both Vulcan/BE4 and Vulcan/AR1 configurations call for 2 engines, which is about 30% more thrust than AtlasV. Removes at least one SRB
Цитировать(Continued). Conversrely, A single AR1 or BE4 config would be about 48% less thrust than AtlasV, which would typically add 2 SRBs. More cost
Цитировать
ЦитироватьStian Nuland‏@Stian_Nuland
@torybruno Won't Vulcan/BE4 require a different tank size compared to Vulcan/AR1 due to propellant density differences? MethaLOX vs. KeroLOX
Yes. LN2 less dense than RP1. Both Vulcan/BE4 and Vulcan/AR1 configs have larger tank than AtlasV to optimize for > thrust: Lower total cost
Цитировать
ЦитироватьStian Nuland‏@Stian_Nuland
@torybruno Thank you. A quick follow up on that. Has the tank diameter been decided? I've heard both 5.4 meter and 5 meter.
5.4. Think of Vulcan as evol of Atlas. AtlasIII got RD180 + bigger Centaur, AtlasV incr to 3.8m + SRBs, Vulcan chg engine and incr to 5.4m
