Editing Fenian Ram (section)

==Design==
''Fenian Ram''<nowiki>'</nowiki>s design was partly modelled on the [[Whitehead torpedo|Whitehead]] [[torpedo]], and it had similar [[cruciform]] control fins near the tail. The boat did not simply take on ballast until she sank like other contemporary submarines; she maintained a slightly positive buoyancy, and tilted her horizontal planes so that her forward motion forced her under.

''Fenian Ram'' was armed with a {{convert|9|in|mm|adj=on|0}} [[pneumatic gun]] some {{convert|11|ft}} long, mounted along the boat's centerline and firing forward out of her bow. It operated like modern submarine torpedo tubes: a watertight bow cap was normally kept shut, allowing the {{convert|6|ft|m|adj=mid|-long}} dynamite-filled steel projectiles to be loaded into the tube from the interior of the submarine. The inner door was then shut and the outer door opened by a remote mechanism. Finally, {{convert|400|psi|MPa|abbr=on}} air was used to shoot the projectile out of the tube. To reload, the outer door was again shut and the water in the tube was blown into the surrounding ballast tank by more compressed air. It was powered by a {{convert|15|hp|abbr=on}} [[Brayton cycle|Brayton]] [[piston engine]].<ref>{{cite web |url=http://www.williammaloney.com/Aviation/FenianRam/index.html |title=Holland Submarine Exhibit, Fenian Ram and Submarine No. 1, Paterson Museum N.J. |first=William |last=Maloney |work=williammaloney.com |year=2012 |access-date=28 August 2012 |archive-date=7 July 2012 |archive-url=https://web.archive.org/web/20120707051618/http://www.williammaloney.com/Aviation/FenianRam/index.html |url-status=live }}</ref>
