Royal Navy urgently requires new air defence capability

The Royal Navy has launched a rapid request for information (RFI) for a new naval “air search capability” capable of countering the growing threat posed by drones, fast jets and cruise missiles under Project ‘Horus’.  

Reflecting an urgent need to meet increasingly complex threats, the navy is prioritising a ship-borne solution for delivery within just six months, according to the RFI issued by the UK Government on 19 March.  

While the exact number of units was not specified, the RFI notes that several platforms will be required to provide coverage across a 2,500-square-km maritime area. 

Although the RFI aims to identify potential systems, it does not constitute a formal competition. Rather, the navy hopes industry will shape the future requirements for project Horus, before any competition or tender is advertised. 

Operational capabilities 

The navy has extensive criteria for the system it seeks, to quickly narrow down any potential options.  

For example, the technology must be able to track and identify airborne threats, including UAS and fighter aircraft at no less than 15 nautical miles. If possible, the system should be able to track uncrewed surface vessels, and fast attack craft at no less than 10 nautical miles. 

In practice, these ranges would give ships the reaction time necessary to counter fast emerging threats. 

Additionally, the navy’s specifications state that the technology must be able to integrate in a ‘system of systems’.  The force is also interested in exploiting existing commercial models. 

Additional requirements 

Other conditions include the need for a robust system that can operate for up to 90 days without maintenance. This level of endurance is key to sustained maritime operations, where deployed vessels require advanced sensors that can function reliably for extended periods. 

The solution must also integrate with current onboard systems, such as the Sapient command and control software – a NATO-standardised interface that supports interoperability between counter-UAS and sensor systems. 

Any manufacturers identified by the RFI will also be expected to support the delivery of the system with personnel training. 

Following the completion of the RFI, future procurement contracts will be advertised on the Defence Sourcing Portal and Contracts Finder. The closing date for the RFI is 31 March.
