LEIDOS SECURITY DETECTION & AUTOMATION U.K. LTD.
LEIDOS SECURITY DETECTION & AUTOMATION U.K. LTD. is a Private limited company (Ltd.) registered in United Kingdom under 03385354, and its current status with Companies House is active. The company was incorporated on 11 June 1997 and lists its registered address as Bedford, United Kingdom. 1 shareholder is on record for LEIDOS SECURITY DETECTION & AUTOMATION U.K. LTD., and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn.

Management authority at LEIDOS SECURITY DETECTION & AUTOMATION U.K. LTD. sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
LEIDOS SECURITY DETECTION & AUTOMATION U.K. LTD. sits 2 levels below its ultimate parent, Leidos Holdings, Inc., registered in United States. 3 subsidiaries are recorded beneath it, across 3 jurisdictions. Immediately above LEIDOS SECURITY DETECTION & AUTOMATION U.K. LTD. is Leidos, Inc., holding 100% as filed in LEIDOS SECURITY DETECTION & AUTOMATION U.K. LTD.'s own shareholder record with Companies House. Leidos Holdings, Inc. sits further up the chain, a link derived by walking shareholder filings across jurisdictions rather than stated in a single document. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 3 subsidiaries span United Kingdom, Ireland, India jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear.
