I hope they change their mind on renaming her. Cosmic Girl is just a good name.

I'm also excited, if surprised, to see this. Could be really good for Stratolaunch. A 747 is, frankly, far better sized and qualified for the work they're currently doing with Talon-A. It's also probably far cheaper to maintain and operate. This might allow them to speed up their test cadence.

Perhaps it will also free up Roc to focus on orbital launch, while Cosmic Girl and Talon-A focus on bringing in actual revenue? Stratolaunch is working with Ursa Major for Talon-A's engine, and Ursa Major did just announce their Arroway engine, which is sized for medium-lift rockets, just like Roc is... seems unlikely since Arroway is pretty clearly designed for a vertically landing rocket, but hey, I guess there's nothing saying you can't have an air-launched, propulsively landing 1st stage. It's food for thought at the very least.

Wait, ∆V? This site will accept the ∆ symbol? How many times have I written out the word "delta" for no reason?

 Stratolaunch got bargain as this 747 is already setup for air launching a LOX Rp1 LV.
Cheaper to fly and maintain 747 plus it gives spare aircraft. If anything had happened to Roc they would've been stuffed.

Since Stratolaunch is acquiring the 747 Cosmic Girl, the pylon below the left wing of the aircraft is to be replaced by a new pylon for the Talon-A spaceplane.

I would not have thought there would be enough room between the inboard engine and the fuselage to carry Talon-A.  Either way, it'll be a tight fit.
With sufficient thrust, pigs fly just fine - however, this is not necessarily a good idea. It is hard to be sure where they are
going to land, and it could be dangerous sitting under them as they fly overhead.

Doesn’t this make ROC rather redundant as this 747 looks a much better fit for their current needs especially the size of vehicle they are currently testing.

Seems like it. ROC is way oversized for Talon A.

Only July 20 Cosmic Girl left Long Beach and arrived at Lake Charles, Chennault International Airport: https://www.flightradar24.com/data/aircraft/n744vg#31391d7a

Sentinel-2 satellite imagery from July 22 shows a white & red 747 outside of a hangar owned by https://www.citadelcompletions.com/about/. The next image on July 27 shows no sign of the 747, so it's probably inside the hangar (as one would expect).

Now I guess we see what comes out the other end :)

For the 1st time as an integrated system, Roc and TA-1 headed outside today ahead of #HurricaneHilary to do some ground tests, including fueling part of TA-1’s propulsion system. TA-1 will be our first powered #hypersonic vehicle, anticipated to fly in the coming months. #LetsRoc

Stratolaunch Announces Contract with U.S. Air Force Research Laboratory

MOJAVE, CA – October 12, 2023– Stratolaunch, LLC announces a contract with the U.S. Air Force Research Laboratory (AFRL) to support the first flight test of the company’s second reusable Talon-A hypersonic test vehicle, TA-3.

Launched from Roc, the world’s largest flying aircraft, Talon-A vehicles are rocket-powered, autonomous testbeds with the ability to fly a variety of hypersonic flight profiles while carrying customized payload experiments on board. Stratolaunch announced its first contract with AFRL in late 2022 supporting its first flight of TA-1, an expendable configuration of the Talon-A product line.

Reusability is an important factor enabling an increase in the cadence of hypersonic testing. Stratolaunch’s repeatable approach enables rapid, iterative testing, increasing the pace of access to the hypersonic environment while reducing development cost, schedule, and risk.

So reusability is important, but the first Talon is going to be  expendable anyway.

Seems like it's defeating the object of the exercise, but it's the USAFRL's dime so at least they are getting some revenue in.

Stratolaunch Awarded Flight Test Contract for the Navy’s MACH-TB Hypersonic Program
Source: Stratolaunch


MOJAVE, CA – November 28, 2023 – Stratolaunch, LLC announces the receipt of a flight test contract award from Leidos, the prime contractor for the Navy’s Multiservice Advanced Capability Test Bed (MACH-TB). The contract award is funded by Naval Surface Warfare Center (NSWC), Crane Division through the Strategic and Spectrum Missions Advanced Resilient Trusted Systems (S²MARTS) Other Transaction Agreement (OTA). This contract award funds five Talon-A hypersonic flights and optional payloads.

NSWC Crane’s MACH-TB program focuses on hypersonic flight testing using robust, agile, and modular approaches. The Leidos-led team intends to deliver an affordable solution, leveraging commercial launch vehicles, including Stratolaunch’s Talon-A hypersonic vehicle, for flight testing hypersonic payloads. The data collected is designed to provide insight to the DoD on technology improvement and capability validation. Early, affordable, and regular hypersonic flight testing is key to robust and successful developments of hypersonic capabilities.

Stratolaunch’s Talon-A, a reusable autonomous hypersonic vehicle, operates as a high-cadence, high-speed testbed to advance the MACH-TB program development. Stratolaunch’s hypersonic contractor-owned and operated flight test service directly complements the goals of MACH-TB.

Quote
We’re excited for the opportunity for Talon-A flights to support the goals of the MACH-TB program and to deepen our partnership with the Dynetics team. The Stratolaunch team is persistently committed to the advancement of hypersonic capabilities for our nation.

Dr. Zachary Krevor
President and CEO of Stratolaunch

Quote
Leidos is delighted to have Stratolaunch join the team that’s working to provide fast and affordable hypersonic flight test capabilities to the nation. Using air launch and the Talon-A reusable vehicle offers unique opportunities to advance the maturity of hypersonic technologies.

Andy Crocker
Leidos Program Manager for MACH-TB

Stratolaunch Successfully Completes Captive Carry Flight with TA-1 Test Vehicle
Source: Stratolaunch

MOJAVE, CA – Dec. 3, 2023 – Stratolaunch, LLC announces the completion of a captive carry flight with the first powered Talon-A hypersonic vehicle, TA-1. The flight was the twelfth for the company’s launch platform Roc and the first in which the aircraft carried a Talon vehicle with live propellant as part of a buildup approach for Talon-A’s first powered flight.

The flight lasted a total of three hours and 22 minutes and represented a significant step forward in the company’s near-term goal of completing a powered flight with the Talon-A vehicle, TA-1. A primary objective was to evaluate Talon-A’s propulsion system and the Talon environments while carrying live propellant. A second objective was to verify Roc and TA-1’s telemetry systems, which provides the situational awareness to ensure all systems are ready for powered flight during the release sequence.

“Talon-A’s propulsion system supports a liquid-propellant rocket engine that provides the thrust needed for Talon-A to reach hypersonic speeds. While we have conducted several successful ground tests fueling and igniting the system, we needed to evaluate how the system performs in the flight environment prior to release,” said Dr. Zachary Krevor, Chief Executive Officer for Stratolaunch. “Initial results from today’s flight show that the system has performed as predicted, and we will determine our next steps pending the full data review of the test.”

Concurrent to TA-1 testing, Stratolaunch is progressing on the manufacturing of the TA-2 and TA-3 vehicles, the first fully reusable vehicles in that Talon-A product line. In addition to meeting this key test milestone, the company also recently announced two flight contracts with the U.S. Air Force Research Laboratory and the Navy’s Multiservice Advanced Capability Test Bed (MACH-TB) program as a subcontractor to Leidos/Dynetics.

“It’s an exciting time for our team and customers as we grow closer to bringing our test service online. We’re moving faster into the future of high-speed flight, and I’m proud of our team’s tenacity to reach this point.”
Dr. Zachary Krevor
President and CEO of Stratolaunch

Welcome home to our newest addition to the air launch fleet, The Spirit of Mojave. The modified 747 was named by the Stratolaunch employees as a tribute to the passion of the Mojave aerospace community that has built and tested some of the world’s most unique aircraft. The Spirit of Mojave symbolizes expanded capability and reach to execute our hypersonic test mission. The aircraft spend a small amount of time on the ground to receive modifications for its new mission and is expected to be operational in the first half of 2024.
