The Boom XB-1, sometimes called "Baby Boom", is a supersonic airplane designed by "Boom Supersonic". The airplane is retired (as of 2025). However, its technology is being used (as of 2025), to finish a new airplane, the Boom Overture.
Test flights (of the Boom XB-1) were done (as late as August 2024). Only one airplane was built; It was for Technology demonstration.
The length (of Boom XB-1), is 21 m (68 ft).
It has 3 jet engines.
The development of the Boom XB-1, is part of the development of the Boom Overture, a transport airliner. In regard to engine for the Boom Overture:
In 2025, Boom announced that it is building a (place or) facility for testing its Symphony engine at the Colorado Air & Space Port. Boom is producing parts for an engine core prototype at its research and development facility in Colorado; Tests on that engine core are supposed to happen in 2026. Earlier (and as of December 2022), the company has an aim (or idea), for production of the engine to begin in 2025 at the Overture factory at Greensboro, North Carolina, according to media.
The Boom Overture will perhaps have its first test flight in 2026, according to media in 2022.
In 2022, a change was made in the design; The airplane will have four turbofan engines, according to the 2022 redesign.

The design (from 2022) will closely resemble (or look a lot like), one from the 1970s, the Boeing B-2707-300.
The Boom Overture will perhaps be introduced [as early as] 2030 or 2029, according to plans from 2022.
