June 10, 20242 yr My focus at the moment is the acoustic (water, sonar) noise created by surface units when group formation is changed. In the current workings of HC when you move a surface unit to a new group formation location (station) it will usually proceed at full speed and thus be very noisy and thus more easily detected by enemy submarines. My usual practice has been if I suspect any likely hood of enemy subs within the region I will go into the unit window and select changing of station units and limit their speed, limiting group speed also if needed to allow the station change to occur in reasonable time. What do others do or think about this situation. I am contemplating looking at a switched speed limiter function for units in a group within my Toolbox add-on and thinking about the 'rules' I would use.
June 12, 20242 yr Author I'll look at doing that. I had an interesting test last night, a 'friendly' USA ssn pair acting as listening enemy and four RAN ships, DDG and FFG in formation. Using my analysis tool AIWindow I watched the change in degree of contact quality by the enemy as I moved ship station with and without restricting its speed (again using tool to restrict max speed. Keeping ship speed below 'cruise' preferably to about 15 kts. made a big difference to enemy getting exact fix as against approx position (test started with approx position known of the test ship changing station. I'm thinking of something where the max speed for station change is restricted to double the current group speed. I have a vague recollection that ships in formation had a restricted speed when group was at 'creep' I'll check that out tonight. (edit) PS, I'm thinking also same thing for ASW station doing sprint and drift, the sprint maybe is too fast? Edited June 13, 20242 yr by donaldseadog
