Narrative:

Aircraft Y was low-level patrolling within the cwf class delta surface area just south of the departure end of runway 15. Cwf requested IFR release for aircraft X off runway 15. I gave cwf the traffic; which was in turn issued to aircraft X; then gave aircraft X a release with reference to the VFR traffic. Given aircraft X's performance characteristics; and past experience; aircraft X should have quickly climbed over the traffic with plenty of lateral separation. However; upon departure; aircraft X executed an atypical climb-out and overflew the VFR traffic with less than minimum altitude separation if the targets had merged.recommend installation of a digital bright radar indicator tower equipment (d-brite) at cwf tower; to prevent excessive coordination and minimize operational errors. Had cwf been equipped with a d-brite; they would have had a better idea of where the VFR traffic was and acted accordingly to prevent any conflict. There is an extra d-brite already acquired; and should have been installed over a year ago.

Title: A LCH Controller reports of releasing an aircraft off one airport and issuing traffic at the same time to the Tower. The Tower knows about the traffic and releases the aircraft. Both aircraft end up with less than standard separation.
