Thank you Ganthu. Yes 1/48 or very very close. (if that's the meaning of the above number).

Yesterday opened up the holes in bow and stern parts for the new larger brass control rods. 3/32 increasing diameter to 1/8 inch (4/32). Color tests of masts. I think tits very close if not exact.

Costs would rise considerably in 3d printing I expect and might make it more likely limiting the available 3 d printers to make the same parts if in 1/32 , the same as the Argonaute which is in 1/32. Most important, it will still fit in the car transporting to the pond. 1/32 Dolphin 2 = 84.37 inches long, (2,143.0mm) 1/48 the scale chosen is 56.25 inches overall. (1,428.8 mm)

Long methodical tests of colors for hte Dolphin occurred in the 3-4 weeks as the parts were being 3 D printed.

LOL. Bingo! Hi Gathu! I deliberately didn't share name at first to see what would happen. having a little fun.

Yes have had drawings on these boats for years (the Dolphin 1 group). Bob Martin was able to fashion drawings nf a Dolphin 2 I was wishing. The Dolphin 1's amazingly are beginning to get old and maybe replaced believe it or not in about 5 years so the Dolphin 2 group (Tanin (trans. "Crocodile" or Tannin) & Rahav (trans. "Splendor" or Rahab).

I think the tragic Gaza war also sparked me into deciding what to build next. Wanted to show some light of these remarkable submarines built by HDW in Keil Germany. Plus, I love the cool camouflage schemes. I also save considerable money; I can use the same transmitter and same WTC by OTW/Nautilus used in the Argonaute in the Dolphin too!

These boats are partly paid for by Germany. A token or gift paying for the tragedies to Jews in WW2 . but wisely also - these boats-maintained continuity of production maintaining Germany's highly skilled specialty work force. Also, perhaps a bit humorously too, I remember the Jewish phrase 'Never buy retail - lol'. Guess this applies to submarine procurement too! LOL. These boats represent Israels most expensive military assets.

They are versatile boats, have AIP (air Independant propulsion) & perform reconnaissance, special operations, anti-ship and antisubmarine warfare, & nuclear deterrence maintaining a potent second-strike capability.

The Dolphin 3's likely will have vertical launch tubes in their longer sail. More are being ordered to replace the three older boats. Germany is now seems very busy, building the Dolphins 3, & a new larger size group of more advanced 212 for Germany and Norway.

The work by Bob Martin designing and printing the parts is excellent. And he delivered remarkably FAST! Thank you, Bob!

Discovered a few minor corrections needed that couldn't be really identified virtually reviewing the work ups together. I wlll enlarge slightly the 3d printed holes in the bow and stern sections for the control rods for the moveable control surfaces. From 3/32" brass rod to 1/8" to beef thm up. (there is room for them) for the control surfaces. The torpedo shutters are off and not enough Adding 4 more to make 10 shutters.

Making templates for the 10 torpedo tube shutters in the bow now.

The stern taper to the 12.5 mm diameter prop hub needed to be 1/4 longer to facilitate the smooth taper.

The bow planes roots int he bows need a small extension, so the moveable bow planes move up and down freely. Otherwise, the rest Bob designed is 'bang on' that I see. The corrections are minor and making these changes now. Impressive work courtesy of NAUTILUS DRY DOCKS.

looks like an Dolphin II class submarine

New Project choice made October 14, 2023. Research sent to Bob Martin. Funds sent.

By mid-November early December, 3D printing took 3-4 weeks. Parts delivered December 16. Some long lead time items already ordered delivered. Use existing transmitter WTC, for great cost savings. Off we go. 5-inch PVC pipe is main structural part, which outside diameter is 5.56 inches diameter. Diameter or beam then is EXACTLY 1/48 scale. PVC bayonet lock rings printed hold bow and stern with access hatches on bottom to access bow and stern plane magnetic connectors. Sent Bob a short sample of the PVC pipe to trail fit parts.
