I don't think the CV was as damaged as some have pointed out, I could be wrong and that can be debated to the infinity.
Dadguns I am a CM and I have access to the raw CM logs.
It
was damaged per those logs to that extent. It was hit by one B17 unloading its bomb load on it and it was hit by bombs from 7 P40Es. The raw logs have several filter options such as objects damaged, objects destroyed, etc.
Others have already addressed the act. You have a smoking burning hulk of a ship. The players know it is a smoking burning hulk because they know a B17 unloaded on it. They know they have struck it with 7 bombs (although the squad in question thought they hit with more than that out of the 10 dropped). They have received multiple kill credits for destroying the soft guns, hard guns, and armored batteries on the CV. The rate of fire coming off the CV is visibly weak to non-existent. So they all this information to go on that the ship basically is a burning gutted hulk.
In real life face with an enemy ship that damaged the pilots basically would have had two choice to make:
1) The ship is basically dead. It hasn't sunk yet but for all purposes it is no longer operational and if it can be salvaged is out of the war for months and months. Worst it might be captured by the enemy. Many ships in this state, including CVs were sunk by their own forces. So don't strafe it trying to kill the crew doing damage control or whatever and don't gamble that a higher enemy fighter force will show up an bounce you while you are low and have expended a lot of your ammo.
Quote From Wikipedia article on the Battle of the Coral Sea
On the morning of the 8th, a Lexington plane located the Shōkaku group; a strike was immediately launched from the American carriers, and the Japanese carrier was heavily damaged. However, Japanese planes penetrated the American defenses at 1100, and 20 minutes later Lexington was struck by a torpedo to port. Seconds later, a second torpedo hit her portside directly abeam the bridge. At the same time, she took three bomb hits from enemy dive bombers, producing a 7 degree list to port and several raging fires. By 1300, skilled damage control had brought the fires under control and restored her to an even keel; making 25 kn (28.8 mph, 46.3 km/h), she was ready to recover her air group. Lexington was suddenly shaken by a tremendous explosion, caused by the ignition of gasoline vapors below, and again fire raged out of control. At 1558, Captain Frederick Carl Sherman, fearing for the safety of men working below, halted salvage operations, and ordered all hands to the flight deck. At 1701, he ordered "abandon ship" and the orderly disembarkation began. Men going over the side into the warm water were almost immediately picked up by nearby cruisers and destroyers. Admiral Aubrey Wray Fitch and his staff transferred to Minneapolis; Captain Sherman and his executive officer, Commander Morton T. Seligman ensured all their men were safe, then were the last to leave.
Lexington blazed on, flames shooting hundreds of feet into the air. To prevent enemy capture, the destroyer Phelps closed to 1500 yd (1371.6 m) and fired two torpedoes into her hull; with one last heavy explosion, Lexington sank
or
2) Strafe a ship in that condition and hope that you will kill the crew doing damage control, that you get lucky and set off surviving bombs, pockets of gasoline vapor that is not already burning, etc.
The second is an act of desperation and real gamble. If higher alt planes showed up you are caught low on the deck and are in serious trouble. However, the CV is a big prize. Suicidal? Definitely running the risk of that. But remember in the battle of Midway that the Devastators of VT-8 decided to attack the enemy carriers without fighter cover. Suicidal but they did it anyway and were all shot down.
So pilot do make judgement calls out of desperation and do or have valued killing a target over the risk of themselves being killed. The Lexington took 3 bombs from dive bombers and 2 torp hits. The CV in question in frame 1 got hit by a B17 unloading on it and then took another 7 bombs from dive bombers. I would say that it was much, much worse shape than Lexington.
