Blue Shark is the code name for a US Navy operation in the Persian Gulf. In addition to providing protection for the USS Nimitz, the HS-6 "Indians," a Navy helicopter squadron, monitors activity in the Gulf and on the waterways in southern Iraq. This is an extended version of a sequence featured in hour 5, "Show of Force," of the PBS series CARRIER, which follows a core group of participants aboard the USS Nimitz, from the elite fighter pilots to the youngest sailors and everyone in between, as they navigate personal conflicts around their jobs, families, faith, patriotism, love and the war on terror. CARRIER premieres Sunday-Thursday, April 27-May 1, 2008, 9:00-11:00 p.m. ET on PBS (check local listings). For more information, visit http://www.pbs.org/carrier
