N585DW · ICAO: A788DB · Heavy jet
GSK plc — British pharmaceutical and vaccines group; 2025 sales £32.7B, up 7% at constant currency. Luke Miels became CEO on 1 January 2026, succeeding Dame Emma Walmsley, who led the company from 2017 and spun out Haleon along the way. HQ in London. The US headquarters is Five Crescent Drive at the Philadelphia Navy Yard — a 208,000 sq ft double-LEED-Platinum building GSK occupies alone — with the major US research weight at Upper Providence PA and Research Triangle Park NC.
N585DW is a 2014 Gulfstream G550 (GV-SP), S/N 5485, hex A788DB. The hex is derived from the registration rather than looked up: the FAA assigns the Mode S code as a pure function of the N-number, so N585DW can only ever be A788DB. FR24 carries the same code.
The registry owner is COLLEEN CORP, which is GSK's own flight department rather than a trustee arrangement — it operates out of Philadelphia International. The GSK link comes from that base and from the spotter record, not from a registry field that says GSK, and that is the standard this attribution rests on. A sister ship, N517DW (2013 G550, S/N 5417), sits under the same entity and is not on this roster yet.
No verified flight history was pulled for this tail, so no frequent destinations are claimed here rather than guessed at. If it flies the GSK site network, expect London, Research Triangle Park, Boston and Washington.
Note · We track GSK's planes, not GSK in person. Flight data shows when and where each plane flew. It does not show who was on board.
