Russian Imperial Navy Submarines in the Russo-Japanese War

It has been stated in the past, that during the period of the Russo-Japanese War, the Imperial Russian Navy had a submarine on strength but no torpedoes for her. However, would the outcome of the war at sea, have changed if the Imperial Russian Navy could have deployed between 4-6 subs, or would the Japanese still have achieved a smashing naval victory regardless?
 
The subs would have to be in the right place at the right time when the war started, the Holland-class boats weren't really well suited to long patrols. Early subs in general, in fact, were more generally considered suitable as a sort of coastal-defence torpedo boat than anything else. So they'd have to be fairly close to somewhere the Japanese ships were going if they were to get a shot at them, and that probably means a port.
Still, the sea of Japan is fairly sheltered, so some brave Imperial Russian commander might have decided to take his boat on a longer and riskier cruise. With only 2 torpedoes, though, they're not going to do a great deal of damage - the effects are probably more similar to a ship hitting a drifting mine than a wolfpack attack. If the butterflies flap in the right direction, that might be enough to have an impact - an important Japanese officer is killed, a vital transport mission delayed, something like that - but I can't see it having a huge effect just in terms of tonnage sunk or sailors killed.
 
Actually, both navies had submarines.

The first mechanically powered series of submarines to be put into service by navies, which included Great Britain, Japan, Russia, and the United States, were the Holland submersibles built by Irish designer John Philip

Holland in 1900. [17] Several of each of them were retained in both the Imperial Russian and Japanese Navies during the Russo-Japanese War in 1904-1905.

The Imperial Japanese Navy (IJN) started their submarine service with five Holland Type VII submarines purchased from the Electric Boat Company in 1904. The five vessels were delivered in sections, arriving in Japan on 14 June 1904. After re-assembly, the five Hollands were ready for combat operations in August

1905, but the Russo-Japanese War was nearing its end by that date, and no IJN submarines would see action in that war.

The first submarines built in Japan were constructed by Kawasaki beginning in 1904. The Kaigun Holland Type #6 and #7 were each launched on 28 September but a year apart, in 1905 and 1906 respectively. Both submarines were modified versions of the original imported Hollands. However, while the original vessels had each displaced over a 100 tons submerged, and were approximately 67' long and 11' wide; the Kawasaki boats displaced only 63/95 tons submerged, and measured 73'/84' by 7' respectively for the number 6 & 7 submarines. The Kawasaki machines had increased horse-power by 1/2, and reduced fuel consumption by 1/4, but could only launch one 18" torpedo and carried 14 men, while the Hollands could fire two 18" torpedoes and operate with only 13 crewmen. The Kaigun Holland #6 submarine has been preserved as a memorial at Kure, Japan.

The Imperial Russian Navy (IRN) preferred the German constructed submersibles built by the Germaniawerft shipyards out of Kiel. In 1903 Germany successfully completed its first fully functional engine-powered submarine, the Forelle (Trout). [19] This vessel was sold to Russia in 1904 and shipped via the Trans-Siberian Railway to the combat zone during the Russo-Japanese War. [20] In 1901 two IRN Lieutenants, Kolbasieff and Kuteinoff designed and built the electric submarine Piotr Koschka which was operated by bicycle pedals, but no other versions were built. During the final weeks of the Port Arthur siege in 1904, the IRN attempted to place the Piotr Koschka into operation, her bicycle pedals having been replaced by an automobile engine. But the attempt to deploy the submarine into the Port Arthur battle was unsuccessful. [21]
 
The Holland was more an experimental class than a proven class.

In fact the first Holland-class submarine to arrive in service with the USN would require an additional 41 months before the USN would actually declare it to be in service.

Even if the first Russian subs were in the Pacific and fully functional with all the needed equipment, including torpedos, I don't see much of a difference being made.

Apparently the Russians had shipped one German-built sub out to Port Arthur before it fell (see my post above). Do you have an opinion on this class?
