Scientists Are Close to Leaning if KIC 8462852 Has ETs There

In 2005, scientists discover an extrasolar planet, which they name Planet G, with conditions similar to Earth. In 2006 NASA transmits a powerful signal from a communications array in Hawaii. Meanwhile, slacker Alex Hopper gets arrested while attempting to impress Sam Shane, daughter of U.S. Pacific Fleet commander Admiral Terrance Shane. Stone Hopper, Alex's older brother and a naval officer, is infuriated at Alex's lack of motivation and forces Alex to also sign up and earn a commission in the U.S. Navy.
By the present day in the year 2012, Alex is a hothead and disrespectful lieutenant and Tactical Action Officer aboard the Arleigh Burke-class destroyer USS John Paul Jones, while Stone is a commander and the commanding officer of USS Sampson. Alex is in a relationship with Sam and is in danger of being discharged from the Navy. Their ships join the 2012 Rim of the Pacific Exercise (RIMPAC) in Hawaii.
During the exercises, five alien spacecraft arrive in response to the NASA signal. Their communication ship collides with a satellite, scattering debris across the planet and crashing in Hong Kong, causing heavy damage and casualties, while the other four (a Mothership and three Stinger ships with red, green and blue sidelights) land in the water near Hawaii. Sampson, John Paul Jones, and the JMSDF Kongō-class destroyer Myōkō investigate. Alex, Raikes, and Beast are sent to investigate, but when Alex approaches, the Mothership reacts and creates a force field that traps the three warships. The Navy issues a blast from a fog horn, which is answered in kind by a sonic blast from the Red Stinger. The Navy fires a warning shot at the alien fleet, which then reevaluates the Earth ships' friend or foe status, changing the monitor color for the Navy ships from green to red. The aliens destroy the Sampson and Myōkō, and damage John Paul Jones, killing the Commanding Officer and the Executive Officer. Alex sees his brother die and returns to his ship, where he is forced to take command as he is the most senior officer left on the ship, albeit reluctantly and to the disbelief of the crew. Enraged, Alex orders an attack, but Beast manages to convince him to recover the survivors from Myōkō, including Captain Nagata with whom Alex is in a rivalry. The Mothership sends shredder-drones to Oahu island to destroy military equipment and island infrastructure, killing some civilians along the way by destroying the freeway leading to a local military base.
