It's appears Rob a draft RFP and not the final RFP.
Per national policy, the Air Force intends to ensure that there are two reliable sources for all nationalsecurity launches
Offerors may submit no more than two proposals per company. Each proposal shall only include oneproposed EELV Launch System prototype. The prototype can be developed using an incrementalapproach, such as achieving the launch capability for Payload Categories A and B prior to achievinglaunch capability for Payload Category C. The Government will award a maximum of one agreementfor one EELV Launch System prototype per company. The Government plans to award a portfolio ofat least three agreements, but reserves the right to award any number of agreements, including none
3.1.2 Section II: Factor 1 EELV ApproachThe Offeror shall describe its approach to develop and qualify a launch system that meets EELVlaunch service requirements. The SPRD and SIS are listed in Annex C, Attachment 4. At a minimum,the Offeror shall address the following topics:1. The ability to meet all EELV reference orbits defined in Table 10 at the orbital insertionaccuracy required in SPRD 3.2.42. The ability to support up to five NSS launches per year3. The ability of the launch system to meet the payload orientation requirement in SPRD 3.2.74. The ability of the launch system to meet the basing requirement in SPRD 3.2.115. The ability of the launch system to meet the EELV mated payload protection requirement inSPRD 3.3.26. The ability of the launch system to meet the payload envelope requirement in SIS 3.1.37. The proposed mission assurance approach to ensure low risk and high confidence in launchingNSS missions8. The ability to slow or surge production to accommodate uncertain NSS, commercial, and civillaunch forecasts
3.1.6.2 Non-Exclusivity of Rocket Propulsion System (RPS) SalesThe Offeror shall provide a signed letter acknowledging understanding of the FY15 NDAA Section1604 (E) requirement that any RPSs developed under this LSA will be available for purchase by allspace launch providers of the United States. The implementation of this requirement is addressed inArticle XIX of the Model Agreement (Annex C). If the Offeror is not proposing to develop anyRPSs under this LSA, the Offeror shall provide a letter with that statement.3.1.6.3 RPS Developed By Not Later Than 2019The Offeror shall provide a signed letter stating whether or not the RPS(s) developed under this LSAare scheduled to complete development by 31 December 2019. The letter shall include a reference tothe related tasks in the schedule (Section 3.1.3.2).
The Government will evaluate the Offeror’s schedule to determine the risk of delayed developmentfor:1. Launch system(s) capable of launching Category A and Category B payloads by 1 October2021 from Cape Canaveral Air Force Station/Kennedy Space Center or Vandenberg AirForce Base2. Launch system(s) capable of launching Category A and Category B payloads from VandenbergAir Force Base by 1 October 20243. Launch system(s) capable of launching Category C payloads by 1 October 2024 fromVandenberg Air Force Base
Quote from: rocketmantitan on 10/07/2017 04:46 amGotta love the Air Force using nautical miles in the requirements documents! Haven't changed in 20 years. Do any of their industrial base or their Aerospace Corporation technical arm even use those units anymore? Probably not. Must be a bit of a pain for industry to rewrite their GNC performance analyses to convert back to nautical miles in order to submit their proposal. Hard to believe that the U.S. adopted the metric system in 1866. Still, nautical miles remain widely used in aeronautics and sailing in the U.S.. - Ed Kyle

Has anyone done an analysis of whether the main contenders (Vulcan, New Glenn, BFR) as currently designed can meet the payloads required for each reference orbit?
I don't think I'd call BFR a main contender for this, the Falcon family would be more likely.
Quote from: gongora on 10/11/2017 03:04 pmI don't think I'd call BFR a main contender for this, the Falcon family would be more likely. I suppose that depends on how seriously you take Elon Musk's claim to transition in the early 2020s away from the Falcon 9/FH to BFR. It doesn't look like SpaceX needs much development money for Falcon 9/FH.

The "MEO 1" and "MEO 2" look like they might also fit in to the "Heavy" category, or what used to be "Heavy". These payloads have increased from today's 1.6-ish tonnes to more than 5.3 tonnes - quite a jump. My assessment is that Falcon 9, NGL 500, and the lower-end Vulcan-Centaur variants can handle the "Medium" missions. (Some of the F9 first stages could be recovered, but probably not all). The "Heavy" missions require Falcon Heavy Recoverable or possibly Falcon 9 expendable, NGL 500XL, or Vulcan with "Enhanced" Centaur. The crossover point between Falcon 9 expendable and Falcon Heavy Recoverable is uncertain to me.FWIW, two-stage New Glenn looks capable of handling any of these missions, Medium or Heavy, but that assumes a long-coast to third restart capability is available. - Ed Kyle

Quote from: TrevorMonty on 10/13/2017 09:48 amBlue's NG would most likely require 3rd stage for GEO 2 mission. At 13t to GTO it only has 6t of fuel to deliver 7t payload plus stage dry mass to GEO. After looking at my model in detail, I agree. New Glenn would need a third stage for GEO and for the two MEO missions. - Ed Kyle
Blue's NG would most likely require 3rd stage for GEO 2 mission. At 13t to GTO it only has 6t of fuel to deliver 7t payload plus stage dry mass to GEO.
New Glenn would also need a launch site for the polar orbit missions. Are there plans for a west coast launch site for New Glenn? Even Orbital has plans to take over Vandenberg SLC-2 (after the last 2018 Delta II mission) for NGL.May the initial plan be launching from the cape at the highest azimuth to the north and then performing a (quite expensive) orbit inclination change with the third stage?
So how many bids can we expect on November 20th? I hope that every established players and new entrants submit their own bids as Prime contractor to maximize competition:- ULA with Vulcan centaur (with BE-4 a priori) and then Vulcan ACES (which upper stage engine supplier?)- SpaceX with Falcon Heavy and then BFR - Orbital ATK (soon Northrop Grumman) with NGL 500 and then NGL500XL. Who will be their upper stage engine supplier ? - Blue Origin with new Glenn (2-stage version) and then New Glenn (3-stage)- Aerojet Rocketdyne with an "Atlas VI" based on AR-1 & RL-10 provided that they should not be part of ULA tea for Vulcan. But who will be their partner for structures and integration ? Any ideas ?
A company can submit up to two proposals, but only one family of vehicles can get chosen according to the documents. That would mean SpaceX could get funding for either Falcon or BFR family, not both. I assume the Air Force would lean towards the one that actually exists already.

The AF Space Command is downright enamored with reusable rockets at the moment,
If I'm reading the conference report correctly this RFP just died. (Can't copy/paste well on phone, will post the text later tonight if someone else doesn't get to it first.)
The amendment would terminate the authority todevelop a domestic rocket propulsion system and to develop thenecessary interfaces of a domestic rocket propulsion system oncethe Secretary of the Air Force certifies to the congressionaldefense committees that a successful full-scale test of adomestic rocket engine has occurred.

This seems to be only about the engine, the RFP is for a launch system so should still stand. Also since Merlin is domestic, wouldn't that terminate the authority right now?

Also since Merlin is domestic, wouldn't that terminate the authority right now?The legislation doesn't provide funding for the program described in the RFP. It explicitly says that spending money on the program described in the RFP is not allowed in FY18. The engine they're talking about is the RD-180 replacement. Merlin is not the RD-180 replacement.
If I read this correctly, no more money for BE4 development? Doesn't seem like that would be a problem however, because BE4 is pretty far along anyway. As far as it applies to the Vulcan LV I supposed BO and ULA would have to work out who pays for development costs. But I don't think it would kill the engine. What does this do to the AJ proposal for vulcan though? Does it make it more or less likely?
"(C) develop capabilities necessary to enable existing or planned commercially available spacelaunch vehicles or infrastructure that are primarily for national security space missions to meet the assured access to space requirements pursuant to section 2273 of title 10, United States Code."
It still allows the Air Force to spend money to Quote"(C) develop capabilities necessary to enable existing or planned commercially available spacelaunch vehicles or infrastructure that are primarily for national security space missions to meet the assured access to space requirements pursuant to section 2273 of title 10, United States Code." (stuff like long coast, vertical integration, launch pads at both CC and Vandenberg, large fairings, etc.)
When is this last bill supposed to be passed ? Why is this RFP not cancelled or postponed in such context where no funding would be appropriated for launch vehicle development ?
Further, the bill defines “rocket propulsion system” as a main booster, first-stage rocket engine, or motor. The term does not include a launch vehicle, an upper stage, a strap-on motor, or related infrastructure.
Another provision in the bill relates to the engines under development for Vulcan. This language states that the Air Force may terminate funding for other rocket propulsion systems when “the Secretary of the Air Force certifies to the congressional defense committees that a successful full-scale test of a domestic rocket engine has occurred.”
Good article by Eric Berger on the NDAA funding language and thus the flexibility it does, and does not, give the USAF:https://arstechnica.com/science/2017/11/a-new-law-gives-air-force-some-wiggle-room-in-picking-its-new-rockets/Two crucial quotes:QuoteFurther, the bill defines “rocket propulsion system” as a main booster, first-stage rocket engine, or motor.

This language states that the Air Force may terminate funding for other rocket propulsion systems when “the Secretary of the Air Force certifies to the congressional defense committees that a successful full-scale test of a domestic rocket engine has occurred.”So first stage funding is fine, but not second or other stages, and AR-1 funding can be dropped once BE-4 achieves a 'full-scale test'.
(e) Rocket Propulsion System Defined.—In this section, the term “rocket propulsion system” means, with respect to the development authorized by subsection (a)(1), a main booster, first-stage rocket engine (including such an engine using kerosene or methane-based or other propellant) or motor.

Mr Berger added a comma there.

1.1. Overview:1.1.1. Prior to 2011, all National Security Space (NSS) payloads were considered as Class Arepresenting the most critical payloads. Launch vehicles (LVs) that launch Class A payloadshave met the highest level of certification requirements with commensurate demonstratedreliability and must have the lowest risk tolerance rating. Class B, C and D payloads areconsidered more tolerant to risk, and can be flown on LVs with progressively higher risk.1.1.2. This instruction defines the process on how payload risk classification will beaccomplished and how the resultant risk classifications are incorporated into the overalllaunch mission risk classification. It provides the SMC/CC the flexibility to certify flightworthiness commensurate with payload risk tolerance. Risk Classification will not takeprecedence over Joint Capabilities Integration and Development System (JCIDS)requirements documentation nor affect system design, acquisition, or build methodologyprior to the launch flow decision process. Unlaunched missions over a year from initiallaunch capability (ILC) will be reassessed annually, to provide opportunity for updated riskacceptance decisions. Payloads introduced to an unlaunched mission under a year from ILCwill reviewed on an individual basis for potential changes to launch mission riskclassification. Consistent mission assurance (MA) will preserve operational flexibility in aContested, Degraded, or Operationally-limited (CDO) environment.

3.1.6.4 Primarily NSS CapabilitiesIn accordance with FY18 NDAA Section 1605, the Offeror shall provide a signed letter certifying that the proposed Government cost share will only be used to develop capabilities necessary to enable existing or planned commercially available space launch vehicles or infrastructure that are primarily for national security space missions.
IMHO, this small addition could be a sign that the RFP was more designed in part to assist SpaceX (among others) in the development of a cryogenic Raptor S2 for Falcon than the development of BFR. Nevertheless, I'm out of my depth here, and would love to hear opinions on the significance (if any) of this small change.

Nevertheless, I'm out of my depth here, and would love to hear opinions on the significance (if any) of this small change.I'm equally clueless but I think the change is made so that the RFP follows the language in FY18 NDAA Section 1605, the change itself has nothing to do with SpaceX or BFR. We can certainly speculate how SpaceX would respond, for example I don't see they go back to Raptor S2 for Falcon. A lot would depend on how everyone involved interpret the text. For example what does "develop capabilities necessary to enable existing or planned commercially available space launch vehicles or infrastructure that are primarily for national security space missions" mean exactly? I'm having trouble parsing this sentence. And what does "development effort necessary to provide the capability to launch Category A/B payloads to NSS reference orbits" cover? Seems to me any work on first or second stage could be argued to be necessary to reach NSS reference orbits.
It looks like the Air Force has already awarded SpaceX $20 million to develop a vertical integration facility, according to this article just published on teslarati.https://www.teslarati.com/spacex-20m-us-air-force-contract-spy-satellites/(Apologies if this is the wrong place to put this. First post!)
$20m is a huge amount for the AF to award SpaceX for a simple "study." For comparison, that's about 25% of what the AF has paid SpaceX for previous launches and contracts.

You made me go look at the SpaceX contracts again (like I didn't have enough to do today, thanks alot). I see about $600M total in publicly known DoD contracts now, which includes four launches (DSCOVR, STP-2, and 2xGPS) and the Raptor development funds.
I think Vc meant 25% of what the AF paid Sx for*one* launch....If we get a few more posts we can carve them out to a new thread.... for now I am not sure this isn't the best place?
The Air Force signed cost-sharing partnerships with ULA, SpaceX, Orbital ATK and Aerojet Rocketdyne. The original request for proposals noted the Air Force wants to “leverage commercial launch solutions in order to have at least two domestic, commercial launch service providers.”The next step is to select three companies this summer to move forward with enginet prototypes.“We are on schedule to make LSA awards in July 2018,” a spokesman for the Air Force Space and Missile Systems Center told SpaceNews.

One thing I'm not certain about in the above article, however, is Sandra's comment that "the next step is to select three companies this summer to move forward with enginet prototypes." If I understood this RFP correctly, the AF would actually be looking to fund three EELV prototypes - they've already funded prototypes of propulsion systems, systems now deep into hot-fire testing. I believe this was where we were anticipating potential proposals for OATK's NGL, Vulcan, FH/BFR/Raptor US, and perhaps even New Glenn.

“If you look at LSA and all those mission profiles, we can serve all of those with a single version of New Glenn with this two-stage architecture,” Mowry said.
Quote from: envy887 on 05/03/2018 07:19 pmAre you assuming the 10% dry mass and 1.0 TWR listed on your site? New Glenn will stage faster than Falcon 9, which only has a TWR of 0.75 at staging. I'm thinking NG will have an upper stage TWR around 0.7, so the stage should mass about 171 tonnes wet. Large LH2 stages get better mass ratios than small ones, so this should be approaching the S-II's 7.2% record. Call it 8%, and the dry mass would be 13.7 t.New Glenn second stage would be roughly S-IVB size rather than S-II size. (S-IVB weighed 120 tonnes give or take, fully fueled.) S-IVB with IU and residuals only had a 0.88-0.89 propellant mass fraction, so I feel I'm being generous with a 0.9 assumption.For a GEO mission, the model wants the final stage to weigh less, not more. The T/W at ignition ends up being higher than 0.75 simply because the stage and GEO payload together end up weighing about the same as the thrust of two BE-3U engines. - Ed Kyle

The highly anticipated LSA selection was originally scheduled to be announced in July but has slipped to “sometime in August,” a spokeswoman for the Air Force Space and Missile Systems Center told SpaceNews....Industry consultant Charles Miller, president of NexGen Space, speculated that ULA may have left the decision up to the Air Force. “My guess is that Tory is basically letting the Air Force choose his engine for him,” Miller told SpaceNews. ULA could have offered two options for Vulcan, one with the Aerojet engine and one with the Blue Origin engine.
WASHINGTON — The Air Force is expected to sign deals with three, possibly four, space launch companies as it seeks to capitalize on private investments and fast-moving technology.Launch Service Agreement (LSA) contracts are projected to be announced in September, according to the Air Force Space and Missile Systems Center....None of the companies would comment for this story due to the sensitivity of the competition. The Air Force first planned to announce LSA awards in July. Industry sources told SpaceNews that the decision was delayed as the Air Force needed more time to evaluate Blue Origin’s bid.
Reading between the lines it seems like the Blue Origin bid showed up quite late, throwing a wrench into the works.How this plays out regarding Vulcan's engine choice will be interesting, and I expect the source of some hot, hot drama.

September is all but over, and as far as I can tell, there’s been nothing more. Anybody heard anything?

Thats a surprise SpaceX missing out. I'd assumed SpaceX and ULA were sure thing with Blue and NG fighting for 3rd place.

A requirement to develop a third stage, or ... may be too onerous.I note that by the time of the first BFS test flights, this contract would only be worth some $200M perhaps.It would be nice to know if SpaceX put in any sort of bid.
I'm surprised. I wonder if this means the end for Falcon Heavy. This seems to be the Air Force ruling New Glenn a better option than Falcon Heavy. - Ed Kyle

Why would the USAF need to pour massive amounts of cash into it for further development? At most it needs a longer fairing and VI, but that's a very minor cost compared to new vehicle development.Or are you assuming that because Atlas and Delta were not funded, that the USAF is no longer planning on using them for EELV?The competition for development money was always Vulcan vs Omega vs New Glenn vs BFR. Falcon Heavy doesn't need development money beyond what it's already getting.

But, if it was BFR that SpaceX proposed, I'll restate to say that the decision endangers BFR. One of them lost big today. - Ed Kyle
The Air Force plans to issue a solicitation for phase 2 in 2019 and make its selections in 2020. Only two will be selected to continue to receive OTA funds. Of the three winners of this phase, the one that does not win phase 2 will not be able to get the full amount of OTA funding that the Air Force announced it would commit.Asked why SpaceX did not make the cut, Will Roper, assistant secretary of the Air Force for acquisitions, said the company is an “important member of our launch team” and can choose to bid again in phase 2.“Not getting LSA funds does not prevent them from competing,” Roper told reporters at a Pentagon news conference.
These contracts are for vehicle development. There was supposed to be another round after this to pick a couple winners to split a certain amount of launch contracts around 2020, for which F9/FH should still be eligible to compete.
Asked why SpaceX did not make the cut, Will Roper, assistant secretary of the Air Force for acquisitions, said the company is an “important member of our launch team” and can choose to bid again in phase 2.<snip>Phase 2 of this competition is “full and open,” he said. “Anyone can come in.”
“The goal of this OTA is to make sure we have a competitive industrial base,” Roper said. His comments suggest that SpaceX may have been left out because its rockets are mature and the Air Force preferred to spend OTA dollars on new vehicles to add to the mix.<snip>In phase 2, vehicles will be evaluated for their ability to meet requirements and schedule but price also will be a factor, Roper said. “We want to makes sure we have at least three vendors that can can compete.”

BFR can't do that without multiple refuelings or an orbital fuel depot, or an expendable third stage which kind of defeats the purpose since that basically makes it a bigger Falcon Heavy.Direct to GEO makes no sense if lift to LEO is super cheap and reliable. But the USAF isn't in that world. Yet.
The twin pads of SLC-3E and SLC-2W, SLC-3W and SLC-2E could be used, but there might be some issues in doing that.

I attempted to find another source or verify the contract, only to find out that the fpds.gov site is a place I never ever want to try and search through again
Quote from: GWH on 10/12/2018 04:43 pmI attempted to find another source or verify the contract, only to find out that the fpds.gov site is a place I never ever want to try and search through again Yeah, I've had that reaction too but you can get a little more used to it over time. The ad hoc reports are really a pain in the ass. I can't afford to subscribe to something like govtribe just for my hobby. My biggest beef with the EZSearch interface is that clicking "View" on an entry doesn't open it in a new tab, that would make things so much easier.FPDS SpaceX search by date range(not sure if it will always keep the sorting options from the URL, on the sort options if you set it to Descending and choose "Date Signed" as the field then you'll at least get the most recent entries first)

It's in the same boat as Atlas and Delta, though for different reasons: it's going to be superseded by BFR for pretty much everything, including, eventually, USAF launches (in my opinion).BFR likely lost. It doesn't meet some of the requirements that the USAF was looking for in EELV-2, such as direct insertion and low technical risk (e.g. very high probability of flying by 2022). There's a reason why "win EELV competition" was never one of the funding ideas that SpaceX threw out there for BFR.
Does anyone for certain know what SpaceX proposed? Would this be classified information? Is some of this information on L2? I just sent a email request to the Airforce and waiting to see what they say. There is always an FOI. If SpaceX did lose, would the recommendations against them be classified?

OTA awards cannot be protested through the appeals channels that exist for traditional contracts.
SpaceX bid its existing, operational Falcon 9 and Falcon Heavy vehicles for all missions set to occur before late 2025 and a newer, even more capable and cost effective system, the Big Falcon Rocket (now Starship), for a tiny fraction of NSS missions to launch no earlier than late 2025.
