Alpha team was an engineering team assigned to the USS Enterprise-E in 2373. Among the Starfleet officers part of Alpha team were Reginald Barclay and Kellogg.
After the Enterprise arrived in Earth orbit in April 2063, chief engineer Lieutenant Commander Geordi La Forge ordered that Alpha team join him in transporter room three for an away mission to Bozeman, Montana to assess the damage done to Humanity's first warp capable vessel, the Phoenix, by the Borg.
