So, in the end, Steam says that I've put 22 hours in the demo. I completed the Coral Sea scenario twice - yes, it takes at least 5 hours of game each time. And I had a blast
Here's a brief review of my last try - the new version of the scenario involving bombers and floatplanes from Rabaul and Tulagi.
I've learned that the Japanese expect me to the west of their position, so I ordered TF-17 southeast at 23 knots, hoping to avoid enemy search in the morning. Yorktown would be responsible for search and CAP - six scouts would launch first thing in the morning, followed by a CAP of six F4F. Meanwhile, Lexington would prepare a full deckload of strike aircraft - 33 SBD, 12 TBD escorted by 8 Wildcats, deferred departure, ready to launch on receiving target information from the scouts.
I find that positioning downwind of the enemy is advantageous. If I end up pursuing, I don't have to change course to launch or recover aircraft. If I end up retreating, the enemy has to turn 180 degrees every time they run air ops, adding 60 miles to our distance each hour.
The scouts launch from Yorktown with the first sunrays of the morning, followed by CAP.
At 0703, the first radio report is received - one of out scouts has found the enemy force about 200 miles to the north. As soon as the enemy carriers are confirmed, Lexington starts launching her strike.
At 0710, an enemy snooper is detected by radar. It has already snuck past our CAP and signaled our position to the enemy. Apparently it was the edge of the Japanese search pattern - we almost managed to avoid it, but 'almost' isn't good enough. At 0719, the snooper - an E13A1 'Jake' floatplane, probably from an enemy cruiser, is finally located and shot down by CAP.
At 0727, Lexington signals that her strike package is underway, and TF-17 returns to eastern course, while Yorktown is spotting her own strike aircraft - 26 SBD, 9 TBD, no escort. At 0752, Yorktown also finishes launching. Only 17 wildcats remain on deck of the two carriers. TF-17 prepares for the incoming strike. (Don't pay too much attention to the time on the screenshots with 3D views - some are from an earlier game where the action developed a bit more quickly in the morning).
At 0808, Lexington air group meets the enemy strike aircraft about halfway to the target. The escorting fighters on both sides engage, leaving both strike packages with significantly reduced protection. A minute later, I cancel the Yorktown CAP and both carriers scramble their fighters to reinforce those already in the air.
