Actor (Captain Esteban) — The Search for Spock

American actor (1939 to 2012) who played J.T. Esteban, the cautious captain of the science vessel USS Grissom, in Star Trek III: The Search for Spock.

Phillip R. Allen, often credited as Phillip Richard Allen, was an American character actor with many television credits, among them a regular role in The Bad News Bears series.
In Star Trek III: The Search for Spock (1984) he played Captain J.T. Esteban of the USS Grissom, the ship sent to study the Genesis planet. Esteban is a by-the-book commander who insists on consulting Starfleet before allowing Saavik and David Marcus to act on their discoveries, and he reluctantly lets them beam down to investigate a life-form reading.
He is still trying to raise Starfleet when Kruge's Bird-of-Prey decloaks and a single over-enthusiastic shot destroys the Grissom with all hands.
