Archibald's Insidious Sub Plot

Just when you thought it was safe to go back into your water proof submarine deck container, the Hansa Brandenburg W20 shows up. Don't worry, she's unarmed.
The W20 was a remarkable aircraft, even more so as she was quite unremarkable, especially for her debut year of 1918. She was quite small and too weak to carry a pilot and a machine gun, thus the benefits of both were weighed and it was decided to go with the pilot and leave the gun at home.
So when the Germans were enjoying Fokker D.VIIs and the like, they were also producing a small, fragile and totally unarmed flying boat. What gives?
That's easy to answer but hard to believe; the W20 was designed to be carried on a submarine and used to scout the local waters for a suitable victim.
The first attempt was simply to strap the aircraft onto the deck of the sub, but it was soon discovered this would prevent the sub from submerging, removing the very essence of its raison d'être.
The next version eliminated the submerging ban when the plane, with its wings folded in, was put into a watertight container and again attached to the sub. This time it worked-in a fashion- but the whole thing was so bothersome it was decided to scrap the whole project and focus on losing the war so everyone could go home and get started on hyperinflation.
Though the German experiment lost steam, it lives on here at 4P Press as an add on station to our popular seaplane expansion to Archibald, Certainly Not! 2, The Long Patrol.
The Add-On
We at 4P are happy to present the clever work of our equally clever guest contributor, Mike McVeigh.
Mike presented us with the idea of bringing in submarine borne aircraft into the game, we said sure, and voila, here it is.
To have a look just hit the download here and start playing, we hope you'll enjoy it.

But Wait, That's Not All
To go along with the add-on, we are also presenting a new database for The Long Patrol that features not only all seaplanes found in ACN2, along with the extra aircraft found in TLP, but also the land based aircraft that were assigned to maritime duties.
