AIRLOCK and FORECASTLE:
Added a small Forecastle to replace the Top Hatch and to factor in a Airlock system that uses an Internal Holding Chamber for cycling. When diving deep the pressure of the water outside of the submarine makes it difficult to vent water to the outside when exiting and entering a sub. This is due to the pressure working against the pumps that are pushing water outside of the craft. As a result I came up with an Airlock system that uses an Internal Holding Tank to mitigate the pressure difference issue. The sequence goes as follows:

NOTE: When below water the Top Airlock Hatches will automatically lock and the only way to open it is to completely fill the Airlock Entrance Chamber with Water from the Holding Chamber. If the Holding Chamber is empty it has a bypass that will pull water from the outside in order to fill the Airlock Entrance Chamber...

To exit the sub below water...
- Enter the Airlock Entrance Compartment at the top of the forecastle. The outer hatch will be automatically locked since the chamber is empty. The Inner Chamber door is on a timer where it will close behind you after 5 secs if you don't close it manually yourself.
- Hit the button FILL button to cycle the Airlock and start pumping in water from the Holding Chamber. The inner hatch will now automatically lock.
- Once the Airlock Entrance Compartment is completely full the system will automatically unlock the outer hatch allowing you to open it and leave.

To enter the sub below water...
- Approach the Forecastle and if the Airlock Entrance Compartment isn't already full then hit the button FILL to start pumping water in to the Entrance Compartment. Note: the outer hatch door will remain locked until it is filled.
- Hit the Open button for the Outer Hatch when it's lock condition shows green and enter the Entrance Compartment. NOTE: the outer hatch is on a 5 second timer and will close automatically behind you if you don't hit the button to close it yourself.
- Once inside with the outer hatch closed click on the DRAIN button. As soon as it starts drain the upper hatch will automatically lock again. Once the Entrance is completely drained the Inner Hatch lock condition light will go green and you can now enter the main part of the submarine.

The system works extremely well for deep diving as the separate large pumps (one for FILL and one for DRAIN) empty the ENTRANCE COMPARTMENT quite fast. Now it doesn't make a difference how deep you dive as the transfer pressure is internal to the sub and not dependent upon the depth. You "bounce" water back and forth between the ENTRANCE and the HOLDING COMPARTMENT at a pressure difference which is like being on the surface.

SUPPORT POD:
I was somewhat optimistic when the large winches indicated they could transfer fluid but that appears to be a typo in interface screen. The Large Winches can only push or pull, not transfer. As a result I abandoned my plans for a support pod that floated to the surface in order to deploy snorkles to pull in air and vent exhaust. The smaller winches that allow for transfer are just too short to be practical. still kept the Support Pod but it is currently less "useful". I added Electric Connections to the top and modified it so that it has two pivotting panels of solar arrays. I may come up with some more "useful ideas" in the future if things changed but for right now it's more a POC (Proof of Concept) gimic.

OBSERVATION HATCH AND SEAT added to glass enclosure beneath sub

WIP Left - Finish Weight Balance and Ballast Settings number; finish build of working manipulator arm pair for bottom of sub that can be operated from OBSERVATION.
