While these boats were serving in Hawaii in the 1920's, some of them carried an unusual visual identification scheme.

The legal provisions of the WWI era construction programs forced the Navy to accept all of the warships that had been contracted for construction during that time.

Design and Construction Notes
The illustration at left is by artist and historian Jim Christley, done exclusively for PigBoats.COM. It shows the general, as built configuration of the EB design for the R-class. The Lake design for this class differed extensively (see below).
While these boats were serving in Hawaii in the 1920's, some of them carried an unusual visual identification scheme. A large geometric shape was painted in white on the sides of the conning tower fairwater. This shape could be seen a long distances, making the boat easy to identify for fleet exercises. The following are the boats that carried the shape scheme and what the shape was:
•R-11: = (two horizontal stripes)
•R-12: X
•R-13: ★
•R-14: ♦
•R-15: ■
•R-16: ●
•R-17: ▲
•R-19: +
•R-20: ǀǀǀ (three vertical stripes)
The use of the shape scheme was limited to the Hawaii area and was abandoned in favor of the boat's name even before they returned to the states.
All of the EB design boats were modified for greater safety in the aftermath of the S-4 disaster. They received escape trunks and hatches, salvage air connections, and the ability to mate with the McCann Rescue Chamber.
The legal provisions of the WWI era construction programs forced the Navy to accept all of the warships that had been contracted for construction during that time. After the war ended, the Navy found itself with more ships than it felt it needed for peacetime operations so scores of ships and submarines were laid up in reserve. The Lake design R-boats were all sent to Philadelphia for inactivation after only about five years of service. They were destined to be scrapped in the early 1930's to keep the USN in compliance with the London Naval Treaty. That same treaty forced the USN to lay up many of the EB design R-boats in 1930-1931. However, the EB design boats were retained, and most were reactivated for service as WWII kicked off in Europe. Several of these boats served in WWII as stateside training submarines. None made war patrols in the Pacific, although a few made anti U-boat patrols in the Caribbean. USS R-12 (SS-89) was lost on June 12, 1943 off Key West due to hull failure. There were just five survivors. The rest of the crew are "on eternal patrol".
The class is broken down by groups below.R-1 through R-14 (EB design built at Bethlehem Quincy)
