... more about S-13,S-14 & S-15 ?.
Nothing more than what's on wikipedia for them I'm afraid.
I guess the Le Grand could be considered a viable candidate for this thread, as it was designed in part for strategic reconniasance
I found this interesting aircraft on the Russian wikipedia
Here are couple of Keburia pix (from five)Hi,
Mr. V.S. Keburiya built a glider aircraft in 1909,also designed and built a monoplane in 1912
or No.2,followed by No.3 in 1913,which similar to Morane but Nieuport-type undercarriage,
who has a pictures or drawings to them ?.
I also know about this project, but... It's, I think, hoax machine. 250 kmph - ok, 1.5 ton load - ok, light metal in construction - ok, but... 12.7, 15.2 mm machine guns, 25 mm cannon... Kurchevskiy gun... And... 5-inch rockets... Leonid Kurchevskiy in this period worked at mechanical catapulte, and, his first recoiless guns - late 1920th. And, "Alexander Nevskiy" - detail of very weird legend about "Ilya Murometz", who destoyed a German tanks by firing of 25-37 mm cannons, and armoured cars by 12.7 mm machine gun. For 9-ton bomber from WW1 it's very big. It's a really heavy drugs. I think, "Alexander Nevskiy" created by one of small-known Russian writer, in alternative history books. And... Where is photos with this airplane? We have many photos with "Svyatogor", but, "Svyatogor" wasn't flying. "Alexander" flying, and we haven't a photos. Where is details of 12.7, 15.2, 25 mm guns? Where is documents? It's one of "unknown wunderwaffe", with K-1000 battleship, nuclear bullets, nazi UFO, etc. Yes, in Russia projected machines with big load, with armour, 3-inch recoiless cannons, light metall, light engines, but... Built this machine in 1916-17? It's not realistic.A project I find very intriguing: The Sikorsky Alexander Nevsky, the successor design to the Ilya Muromets
If anyone can find pictures I'd greatly appreciate itThe Sikorsky Alexander Nevsky ( ru. Александр Невский) was the only Russian four engine bomber biplane of its kind, designed and built by Igor Sikorsky in the late 1916. It was named after a Russian prince Alexander Nevsky.80% of the Alexander…enacademic.com
Well damn, wish I saw that. And no, I don't get my shit from alternate history websites, several sites mentioned it and the closest thing I could find to someone saying it's a fake project was someone suggsting it's just a mix up wit an ilya muromets called the Alexander Nevsky. My apologies.Read carefully

I haven't drawings of this projects, with the exception of Abramson project, only descriptions, from book, "Helicopter of pre-revolutionary Russia", V. Miheev, 1992.can you show their drawings ?
Also, other analogical projects:Perhaps you're thinking of Nikitin? The Nikitin-Shevchenko IS-1 fits your description.
