The 1st Cruiser Squadron, formerly Cruiser Force, was a unit of the SDF-Navy dedicated to operating the six light cruisers of the Rhiannon-class from 1928 to 1998. With the scrapping of the five remaining light cruisers (SDFS Lodan Lir was sunk in 1983, on the first day of the Second Vellenge War), the 1st Cruiser Squadron was disbanded.

In late 2017, with the introduction of the Maighdean-class Missile Cruisers, the 1st Cruiser Squadron was re-established and homeported in Wembury. The Squadron is composed of three vessels, SDFS Maighdean, SDFS Bruinneall and SDFS Cailín.
