Flight of two; a gulfstream ii and a falcon 20; lost visual contact shortly after takeoff and executed a lost wingman procedure which compromised their IFR clearance. ATC assigned a separate transponder code to the second aircraft and assisted in rejoining the flight.

Narrative:
Flight of 2 aircraft departed on an right&D mission. Lead aircraft was a falcon 20; wingman was a G-2. The falcon departed first; the G-2 second using a 15 second in trail procedure; intending to join on the falcon's right wing. During climb; prior to join-up; ATC issued a heading change from 290 degrees to 070 degrees. Lead aircraft speed was 220 KIAS. As lead turned; closure rate increased and wingman lost sight of lead. Wingman initiated lost wingman procedure; i.e.; right turn to a divergent heading; maintaining a lower altitude and maintaining 'see and avoid' for other aircraft. Efforts were made to regain visual contact with lead to accomplish a rejoin. ATC became aware of the situation and had wingman squawk a separate transponder code. In retrospect; notifying ATC in a more timely manner would have been desirable. In the future; more emphasis will be given to more thoroughly brief flight crews in all aspects of formation flight.
