Task Force is a 1949 American war film filmed in black-and-white with some Technicolor sequences about the development of U.S. aircraft carriers from USS Langley (CV-1) to USS Franklin (CV-13). Although Robert Montgomery was originally considered for the leading role,^[3] the film stars Gary Cooper, Jane Wyatt, Walter Brennan, Wayne Morris, Julie London and Jack Holt. Task Force was the only film Gary Cooper and Jane Wyatt made together, and was the last of the eight films Cooper and Walter Brennan made together.^[4] The U.S. Navy provided complete support in not only lending naval vessels and facilities, but also allowed the use of archival footage of the development of naval air power.^[5]

As a 1917 graduate of the Naval Academy, Naval Aviator Jonathan L. "Scotty" Scott (Gary Cooper) spends 28 years, from 1921 to 1949, promoting U.S. naval aviation and the power of the aircraft carrier. During that period, he antagonizes powerful people in the U.S. Navy and the U.S. Congress, and marries Mary Morgan (Jane Wyatt), the widow of a fellow flier who died in a crash during a carrier takeoff aboard USS Langley (CV-1). Throughout, Scott has the help and friendship of his mentor and superior officer, Pete Richard (Walter Brennan).

The Scotts spend two years in Hawaii and then move to Annapolis, where Scott, now a lieutenant commander, is to teach naval aviation but his outspoken stand in favor of aircraft carriers in combat causes him to lose a promotion. After Japan invades Manchuria, Scott is offered a civilian sales position selling aircraft in Europe, but remains in the Navy.

After Pearl Harbor is attacked by the Japanese, Scott's ship, USS Enterprise, is heavily involved in action at the Battle of Midway. Scott later travels to Washington D.C. to plead for more carriers and eventually a carrier fleet is produced. During the Battle of Okinawa, the fleet, with Scott as the captain of the carrier USS Franklin, proves its worth. When his carrier flight deck is badly damaged by Japanese torpedo aircraft, the ship is forced to withdraw to the U.S. for repairs and the war ends when they arrive in at the Navy Yard in New York City. Four years after the end of the war, Scott, as a rear admiral, retires and joins Mary, who is waiting for him on the dock.

While much of the archive footage used for the ship commanded by Scott was of the USS Franklin, the actual situation more closely resembles the attacks on USS Bunker Hill. Especially as in real life, Franklin had already been knocked out of the war before the invasion of Okinawa began.

In 1948, Warner Bros. obtained archival U.S. Navy footage documenting the rise of naval aviation as well as Technicolor footage filmed during the war in the Pacific, including the Battle of Midway, the Japanese attack on USS Yorktown and a kamikaze attack on USS Franklin.^[7] Encouraged by the offer of support from the U.S. Navy,^[5] when the production received permission to proceed with a film, a decision was made to shoot the first segments in black-and-white to merge into the original footage of the USS Langley, the first American aircraft carrier, and USS Saratoga.^[3] Principal photography began in late 1948 on the escort carrier, USS Bairoko to replicate USS Langley, as well as Naval Air Station North Island in San Diego.^[8] The U.S. Navy provided access to naval facilities with costs amounting to as much as $24,000 a day ($304,400 today) being incurred when an admiral's barge and jet fighters were commandeered.^[9] Additional work took place at the Burbank studios to cover interiors and process shots. Production finally wrapped on January 5, 1949.^[10]

Near the end of the film, the film changes from black and white to Technicolor in order to unobtrusively use actual combat film shot in color. The change comes just after a scene showing a contentious meeting in Washington D.C. in which Brennan and Cooper argue with a senator who wants to stop building carriers. After some aerial shots of a task force at sea and an aircraft landing on a carrier, still in black-and-white, a shot of a sailor in combat gear silhouetted against the sky is in color, but filtered to make it sepia, a technique similar to that used on the transitional shot of Dorothy opening the door of her house to reveal Munchkinland in The Wizard of Oz. This is followed by Cooper at night walking the deck of his first command, still in sepia, and aircraft taking off at night. The next shot, of a naval task force with air cover, is in full color.^[11]

Complications set in during the filming of Task Force as consecutively, four separate crews were at work with the resultant task of merging all of the live action and archival footage. One of the near disasters involved a delivery truck that caught on fire with its load of cut and stock film along with daily rushes, personal baggage and makeup destroyed. More serious was a series of accidents involving the star, who had already expressed reservation both about the script and his perceived inadequacies as an actor.^[9] In December 1948, Cooper was on a navy barge that broke down in fog, and began to take on water, almost foundering on the rocks in Long Beach harbor before he was rescued by a navy ship. Cooper was subsequently hospitalized with a high fever.^[12] He was nearly seriously injured on another occasion. During gunnery practice, when Cooper was on USS Antietam, an unmanned target aircraft was hit and caught fire, heading for the crowded deck where all of the actors and crew were standing before skimming overhead, and crashing in the ocean.^[9] Wayne Morris who portrayed Lt. McKinney was the only actual carrier pilot in the cast and served on the USS Essex, becoming an "Ace" by shooting down 7 Japanese planes and assisting in the sinking of 5 Japanese ships.
