Key Takeaways:

Stratolaunch's Roc, the world's largest airplane by wingspan, is preparing for its fifth test flight, primarily to evaluate its newly attached carrier pylon.
The pylon is crucial for Roc's core mission: to transport and launch Talon-A hypersonic testbeds during flight.
Talon-A vehicles are uncrewed, rocket-powered aircraft designed to reach speeds of Mach 5 or faster for hypersonic research and "threat replication" for customers like the Pentagon.
Successful pylon testing is a key step towards Talon-A's anticipated first hypersonic test flight by the end of this year, with operational capability projected for mid to late 2023.

Stratolaunch’s Roc returned to the airfield at Mojave Air and Space Port (KMHV) this week, as crew members prepared the world’s largest airplane by wingspan for a crucial flight to test its new carrier pylon.

The one-of-a-kind aircraft powered by six Pratt & Whitney PW4056 engines, and with wings measuring longer than an NFL football field was spotted Thursday performing low-speed taxi tests. But unlike previous excursions, this was the first time Roc was seen with an attached pylon, which is designed to carry and launch hypersonic Talon-A testbeds.
