Gravitilab UK goes bust

UK would-be suborbital rocket builder Gravitilab has entered liquidation, leaving more than £700,000 (€818,000) owed to its creditors. An announcement says that the company has ceased trading.

Documents filed with Companies House show that Gravitilab’s shareholders approved a voluntary winding-up at a general meeting held via Microsoft Teams on July 20th. The filings outline that the company is undergoing a voluntary liquidation and that the liquidators, Price Bailey, were appointed by its creditors.


Reportedly, the company’s position was not helped by a promised major investment which failed to materialise.

Gravitilab stated that it had expected an investment from Finnest Group, an early-stage private equity and venture capital firm, but which is being wound up in accordance with a decision made by the UK High Court in 2025 although some of its investments are now included in BNP Finnest which continues to trade.

Gravitilab had reportedly been developing a suborbital launch vehicle called ISAAC that would have been powered by a hybrid propulsion system. The rocket was designed to carry payloads of up to 20 kilograms to an altitude of 170 kilometres. According to its website, the rocket was expected to enter operational service by 2025, a milestone that never came to fruition. The company did, however, complete at least two test flights. The first involved a vehicle called Peregrine during an aerodynamic flight test in Australia in 2020. The second used a rocket called ADA, which was launched in August 2021.
