Task Force Betawi was a Starfleet task force extant in the early 23rd century.
The Sadat-class USS Accord — commanded by Commodore Indra Suleiman — was part of Task Force Betawi, which battled Klingon forces in defense of New Ruritania in 2231. Accord sustained heavy damages and was destroyed by a warp core breach. (Star Trek: Accord: "The USS Accord Fictional Timeline v. 3.0")
