The ground support echelon of the 509th Composite Group received movement orders and moved by rail on 26 April 1945, to its port of embarkation at Seattle, Washington. On May 6 the support elements sailed on the SS "Cape Victory" for the Marianas, while the group's materiel was shipped on the SS "Emile Berliner". An advance party of the air echelon flew by C-54 to North Field, Tinian, between May 15 and 22, where it was joined by the ground echelon on 29 May 1945. Project Alberta's "Destination Team" also sent most of its members to Tinian to supervise the assembly, loading, and dropping of the bombs under the administrative title of 1st Technical Services Detachment, Miscellaneous War Department Group.
