This contract was not competitively procured pursuant Federal Acquisition Regulation 6.302-1.

Pretty feeble justification.

The SBIR data rights issue: ordinarily, after 5 years they would revert to unlimited rights for the government but because
the Navy keeps feeding OATK/NG under the SBIR Phase III contract it keeps resetting the expiration period.

The propulsion section justification boils down to: the Navy thinks it's too hard to manage the contract.

Military / Re: US Prompt Global Strike Capability

"In enemy hands, the new class of hypersonic speed maneuvering missiles may pose the greatest threat to the U.S. Navy’s heavily defended battle groups. At the same time, designing a hypersonic glide vehicle compatible with a submarine’s underwater launching system presents the hardest engineering task in a technology area that has eluded American mastery for decades.

It is perhaps no surprise, then, that the $10.5 billion war chest wedged into the Defense Department’s latest five-year spending proposal is dominated by the Navy’s Conventional Prompt Strike (CPS) program. Fulfilling its two assigned tasks—developing a common hypersonic glide vehicle that can be adapted for ground- and air-launch, plus demonstrating a sea-launched version with an integrated booster and glider—consumes about 55% of all U.S. military spending on offensive and defensive hypersonic weapons technology over the next five years, budget documents show.

"Roper notes that he wanted a program to come out every three years. “We would never get relief on schedule. We would trade performance to hold to schedule. And I love that idea for the Air Force,” he said.

The fiscal 2020 budget proposal seeks to usher in a new era of long-range high-speed missiles. A $10.5 billion plan to develop a series of prototypes for hypersonic boost-glide vehicles has captured most of the attention, but the budget submittal also proposes introducing a wide range of new air- and ground-launched missiles.

A portion of the classified NGAD program has been devoted to developing new weapons to augment the capabilities of existing air interceptor missiles such as the AIM-120C/D and AIM-9X. In fiscal 2020, the Air Force wants to launch the first “scaled flight demonstrations” for a new generation of air-launched weapons, including miniature self-defense munitions and “multishot” air-to-air weapons.

The latter was formerly known as the Small Advanced Counter-air Missile (SACM), but has been renamed within the Air Force Research Laboratory as the Counter-Air Science and Technology (CAST) program. While SACM was focused on developing a missile half the size of the AIM-120 but with similar range, CAST takes a broader approach. Under CAST, the same technology that enables AIM-120-like range in a vehicle half the size can produce a weapon with double the range in a similar form factor."

New FAA NOTAM restricts airspace around SpaceX’s South Texas launch site Monday-Wednesday next week “for rocket launch and recovery”. Airspace restricted up to an altitude of 1,000 feet. Looks like they’re getting ready to hop… http://bit.ly/2JxnU5S

DIT Trade Showcase to SpaceX in US

21 March 2019 – The Department for International Trade is organising a UK Technology & Capability Showcase for SpaceX in late spring or early summer 2019 (date to be confirmed later) at SpaceX’s HQ in Hawthorne, California.

The SpaceX technology development and procurement teams for the Starship (formerly known as the BFR) and Starlink programmes will review UK supplier capability descriptions and select the participants. Therefore, if you have a UK-based capability that you think SpaceX would be interested in, please register for the event and submit your capability summaries.

[...]

In addition to the best of UK’s capabilities that we will be offering to SpaceX, they have identified some specific capabilities and technologies that they require. If you can satisfy any of these needs, then you should certainly submit a set of forms:

Pressure & Motion Controls, Actuation (“Vendor IP”):

1. Solenoid Valves for high vibration, low and high temperature environments

Strong and nimble engineering departments
Environmental analysis on site is a plus (vibe testing greater >90 Grms)
2. Brushless DC & Inductance Motors for high vibration, low and high temp environments

Same features as the above Valve category
Machining/Fabrication:

3. Spline/Gear machining (preferably located in or near other machining suppliers, think turn-key turbomachinery shafts)

4. Turbomachining (blades, impellers that are smaller than a 24” cube)

5. Large OD tube bending >8” OD

6. Shaped or Formed Flexible Hoses (primarily Kevlar braided Teflon hose that is formed to a particular shape to reduce stress)

7. Aerospace Metal Bellows formed with new technologies (standard technologies are mechanical forming, edge welding, hydroforming, or electroformed – looking for any new technologies or suppliers that may excel with the current technologies)

Castings/Raw Materials:

8. Specialized castings (new innovative casting methods)

9. Die casting suppliers

10. Specialized materials (for extreme environments)

Avionics:

11. Large format PCB fabrication and PCBA assembly (>30”)

12. Solar panel assembly[/quote]
