Research submarine Delta - the original:

The research submarine Delta is a small two-man research submarine. It is operated by the company Delta Oceanographics in California.

Since entering service in 1984, the Delta has successfully completed over 6,700 dives without incident. This makes it one of the most frequently used and most efficient research submarines. Due to its small size, the submarine is very flexible and can be used almost anywhere without great effort.

With the small submarine, depths of up to 360 meters can be reached. The oxygen for the crew is sufficient for a good 140 man hours.

During the diving trips a broad spectrum of subjects was covered. In addition to dives for research purposes, dives were also made for historical wrecks and treasures.

The submarine is also used to check and inspect pipelines and drilling platforms. The delta is also sometimes used to support fishing or to prepare precise underwater maps.

Research submarine Delta - the model:

The model is a 1:8 scale kit. This kit can be ordered via Model-Submarine-Specialties in Germany. With this kit you can build a fully functional, statically diving submarine.

The base of the Delta:

My model was built over the years 2009-2010 from the kit, which provides a very solid base.

In addition, miniature screws for detailing the windows and various other small parts can also be ordered at Model-Submarine-Specialties as well.

The details of the Delta:

In order to give the model a special touch and to achieve an appearance that is as true to the original as possible, numerous other details are attached.

The underwater cameras and microphones mounted on the boat for diving operations have been reproduced like the original. The cable routing along the fuselage was also taken from various original documents and implemented on the model.

In addition, the lighting, consisting of 11 lights and a spotlight on the tower, is also fully functional.
