## Description

DARPA TTO is sponsoring a Proposers Day to provide information to potential proposers on the objectives of the TTO Office-Wide (OW) Solicitation, DARPA-PS-26-123, published on SAM.gov. TTO seeks to redefine warfare to provide overwhelming advantages to the United States by accelerating the development of new classes of platforms and weapons that dominate existing battlespaces and define new ones at a velocity that adversaries cannot match. Potential proposers can reference the solicitation for research areas of current interest to TTO.
