Essentially the U.S. had been looking for an excuse to participate in the war without looking like the "bad guys." Wheras the Japanese assumed that the U.S. would be incapacitated by the attack, what they didn't know was that most of our aircraft carriers were at sea and we were not in fact incapacitated.
I'm assuming you mean what long-term materiel losses resulted from the attack. While the US Army Air Corps lost hundreds of planes, these were fairly easily replaced. The US Navy had 18 ships either sunk or damaged during the attack. Of those, only 3 never saw any action again. The USS Arizona and USS Utah still lay on the bottom of the harbor. The USS Oklahoma capsized during the attack, was refloated, and was being towed to San Francisco when is sank during a storm. All other ships were back in action by the end of the war.
They thought they would be able to render the U.S. Navy Fleet useless, but many of the ships were at sea already. The Japanese gained nothing (but a surprise attack at Pearl Harbor causing many deaths and sinking many ships not to mention destroying planes and buildings) but, they realized that because their plan back-fired they had WOKEN THE SLEEPING DRAGON! This meant their plans had not gone well, they had failed and they were at the mercy of the powerful Americans. Thus the H Bomb on Hiroshima and Nagasaki.
About three thousand military personnel, mostly Navy, were killed. Additionally 18 US warships which included the west coast battle ship armada were lost note-ably the USS Arizona which exploded after a bomb hit it's magazine. There were several buildings damaged and aircraft hangars as well as several aircraft. Mostly, I think America lost her innocence. Most Americans believed we were completely safe from all of the other war activity going on with Germany in Europe and Japan in the far east.
Besides the US Pacific Fleet in Pearl Harbor the Japanese attacked every Army Air Force and Navy airfield on Oahu, as well as Schofield Barracks Army base. About 160 US aircraft were destroyed.
Over 2400 US personnel were killed, almost half on the USS Arizona, which blew up, and another four hundred on the USS Oklahoma, which capsized, trapping hundreds inside its thickly armored hull.
The Oklahoma and the Arizona, along with the USS Utah, were the only ships permanently lost in the attack. The Utah was an old battleship which had been converted into a target ship. The Japanese probably mistook her for a carrier, as her main guns had been removed and her deck covered with heavy timbers. The Utah and the Arizona remain on the bottom of the Harbor on opposite sides of Ford Island. The Oklahoma was finally refloated in 1947, but sank while under tow to the mainland.
There were about fourteen ships damaged in the attack, some very seriously, including the battleships California and West Virginia, which sank, but were easily refloated in the shallow Harbor, repaired, and soon back in action.
