The UK Ministry of Defence (MoD) said on 7 November 2026 that Titania, the second satellite launched under its Istari space-based intelligence, surveillance, and reconnaissance (ISR) programme, had reached orbit.
The approximately 100 kg satellite will be operated by UK Space Command. It was designed and built in Hampshire through a partnership between the MoD's Defence Science and Technology Laboratory (Dstl) and BAE Systems under a GBP9.5 million (USD12.7 million) contract, according to the MoD.
Titania was launched aboard a SpaceX Falcon 9 rocket on the Transporter-18 rideshare mission from Vandenberg Space Force Base, California, on 1 October 2026. BAE Systems confirmed Titania's inclusion in the mission in a 9 November statement.
BAE Systems described Titania as an operational concept demonstrator that will test how sensors operating across different parts of the electromagnetic spectrum can gather information to support military operations.
The satellite follows Tyche, the first spacecraft launched under the MoD's space-based ISR programme. Designed and built by Surrey Satellite Technology Limited (SSTL) under a GBP22 million contract, Tyche was launched on 16 August 2024 aboard the Transporter-11 mission from Vandenberg. The 150 kg satellite was designed for a five-year operating life in low Earth orbit, providing daytime imagery and video of the Earth's surface.
Further Istari spacecraft include Juno, being developed with SSTL, and Oberon, with Airbus Defence and Space. The programme will combine satellites and supporting ground systems to expand the UK's sovereign ISR capability.
