No, there is no way to bring up the orders in game. There should be, as Captain would have them at sea. Best is to prior to starting patrol type them up in a text doc or do a screenshot. I usually take a photo with phone and type up in a text doc for reference on patrol and for later patrol report.
Pre-War missions I added are a mix of history based pre war exercises and patrols I read about and some "what ifs" but are not impossible that occurred or could have.
The exercise missions for example, are based on historical actions by US subs. The Pearl based boats may be assigned to conduct ops with carrier task force , which they did in pre war as the fleet boat was originally designed to operate with the fleet. These subs would also provide practice targets for the escorting DD's and vice versa.
In Asiatic the exercise with Marblehead is based on history. During research I read some subs engaged in exercises with her and other vessels.
Subs typically fired practice torpedoes, set to run below keel of target, if torpedo wake went below target, it was considered a hit. Practice torpedo at end of its run would float to top and could be recovered. Early on, there was a recovery vessel in area but later subs carried gear and recovered their own practice fish. Obviously the recovery aspect can not be simulated but can fire the MK 10 as practice fish to simulate these exercises.
If you are assigned a "depth charge indoctrination" in training, these units will attack you, so stay out of sight surfaced and will attack with depth charges. I included a practice depth charge mod to activate before going to sea.
A mission that will be in next release is for Gar New Construction in 1941. Gar class boats were used to test the effects of depth charges on new fleet boats in summer 1941. Believe it or not, first such tests conducted by US in history.
Other orders such as patrolling off home islands to observe shipping etc are fictional as to my knowledge none of our subs conducted such patrols, but figured its possible they could have and would prove interesting in the sim.
I did place objectives to give player chance to run into enemy forces and depending on where and when, they may be hostile if detect, or may not.
Movements of the Akagi are scripted, so player may catch the carrier when underway after her refit in summer 1941, as well as other carriers on training. Can catch them departing for the Kurile Islands where the carriers that would strike Pearl Harbor assembled prior to departing for the strike.
The invasion of French Indochina in July 1941 is scripted, player has chance to get orders that put them in position to possibly encounter said force. They may be hostile or may ignore, had it go both ways during testing.
Marblehead not showing up was a issue in testing, sometimes it showed up, sometimes it did not, not sure exactly why but have a idea. Plan to take another look in next version.
