Air Force’s rocket propulsion arm looking to invest in technologies for ‘responsive launch’

Quote from: SpaceNews
The Air Force Research Laboratory’s rocket propulsion arm is asking space companies to help identify technologies and capabilities the military will need to launch missions on short timelines.

The organization known as AFRL’s “rocket lab” based at Edwards Air Force Base, California, is “soliciting information and comments from industry on their ability to meet future responsive launch missions and to identify specific investments in technology that would improve responsive capabilities,” said a request for information published last month.

The request said AFRL is not looking to address any specific national security launch requirements but wants to better understand what technologies and capabilities are available and which ones need to be developed to help shorten the time it takes to plan and launch space missions.

The Dutch have studied using their F-16s for nanosat launch.  I’ve long thought that if the USAF/Space Force became serious about a true, wartime launch capability, we’d build solid upper stages that could be launched by stripped-down QF-4/QF-16/QF-15 target drones.  Maybe even modify the drones with MIPCC and a long nose boom to boost performance, as NASA has studied.  With microsats waiting on the ground, would provide a standby capability that could be launched with hours notice, vice days to weeks for the commercial SLVs, from dispersed locations for rapid replenishment of on-orbit capabilities.

Orbital velocity is mach 23, with large external payload mach 2 would be about it for a jet. I doubt 2 stage SRB would be enough.

The Dutch study is three-stage on an F-16.  Per Mehta’s study, an QF-4 with MIPCC hits Mach 2.5 around 60K ft.  Even with poor upper stage drag, the satellite payload is measured in the 100-200lb range.  When they start to be converted, QF-15s would do even better.

Space Force to select small rocket for ‘responsive space’ mission [May 12]

Quote from: SpaceNews
The U.S. Space Force plans to select a small satellite launcher to fly a payload to low Earth orbit on short notice, a capability known as tactically responsive space.

The Space Force’s Space Systems Command on May 12 announced it plans to award a contract in August for the Tactically Responsive Space (TacRS-3) mission.

<snip>

TacRS-3 will be managed by the Space Force’s Rocket Systems Launch Program. Vendors that were pre-selected for the Orbital Services Program OSP-4 will compete for the task order.

<snip>

The selected launcher will deploy a space domain awareness payload called Victus Nox.

For the next mission, which Space Safari has named “Victus Nox,” the Space Force wants to broaden its scope from focusing on launch to looking more closely at the supporting elements of responsive space. At the same time, it wants to compress the launch call-up period to just 24 hours from three weeks. The mission doesn’t have a set launch date, but the program office is targeting mid-2023 and expects to award a contract for the rocket by the end of the summer.
