busch sulzer – Vintage Diesel Design

I have two c. 1944 advertisements in my collection – both featuring a Type 327 ST tug, built for the US Army, one from Enterprise, and the other from Busch-Sulzer.

You will note….both advertisements feature the same tug, ST-246! These 86′ Type (design) 327 tugs were built throughout WWII by numerous shipyards across the country and used 3 main types of propulsion, all of which were direct reversing engines:

Enterprise Engine & Foundry Co. – DMG-38: 8 cylinder, 12″ x 15″, 650HP
Busch-Sulzer – 6DFMT-17: 6 cylinder, 13″ x 17″, 650HP
Clark Brothers – MD-6: 6 cylinder, 12 /2″ x 16″, 650HP

It is likely that both of these companies used a stock photo provided by the Army, however it is indeed good for a laugh. A good portion of these tugs went on to postwar careers, many of which would get EMD 567ATL repowers. The Great Lakes region is home to a handful of these, as well as some with original Enterprise engines. The Enterprise seems to have been the better choice of the three. Other classes of ST tugs built during WWII featured a swath of other engine makes, including EMD, Atlas Imperial, Cat, Superior-National, Buda, Kahlenberg, Fairbanks-Morse and others.

According to Dan Friend’s roster – the 246 had the Enterprise (and may still be around!) – https://www.usarmysttugs.com/uploads/3/3/1/4/3314314/ww2_st_st_9_-_937__9_26_2014.pdf
