Non-magnetic Marine Diesels

Post by Dave Czirr » Fri May 07, 2010 6:00 am

I've always considered the V8, V12 & V16 non-magnetic marine diesels Packard built for the Navy for mine-sweeper use as the least-known Packard marine engines. I'm told some of these were in service as late as the first Persian Gulf war. I believe (not positive) that these pictures snitched from eBay are for cylinder sleeves and heads for one of these engines. Excellent source of information on these engines is in Robert Neal's "Master Motor Builders".

According to Robert J. Neal’s wonderful “Master Motor Builders, as late as 1994 the U.S. Navy still had 4 minesweepers in service with their original Packard V-12 marine diesels (1D-1700) and 4 others, also still with Packard power, had been sold off to the Spanish Navy. Apparently all those with the Packard V-16 marine diesels ((1D-2270) had been retired or sold off. These engines and the companion 1D-850 diesel electric generator were made almost entirely of stainless steel, aluminum and bronze to maintain the non-magnetic requirements for minesweeping. Can anyone update us on whether any of these vessels are still in the U.S. Navy, active or in standby, with their original Packard engines.

We have a contributor who has been very deeply involved in restoration of Packard marine engines and has promised to contribute some interesting information, so if this is a topic that interests you, stay tuned and check in frequently. And please chime in with you own contributions or questions - this topic is a very interesting segment of Packard's history.

How interesting !!

I had no idea that Packard made non-magnetic diesels like this. What was the hull made of??

According to the description given in the Cormorant News Bulletin included above, the hulls were made of wood.

According to Robert J. Neal's book, only 8 of the 1D-1135 (V8) and 5 of the 1D-2270 (V16) were made, in 1952. The volume engine was the 1D-1700 (V12) of which 451 were produced between 1952 and 1956. There were also in-line 6 (1D-850 and 2D-850) versions, about 294 produced thru 1956. All were turbosupercharged and the V12 version produced 600 hp. Neal's book contains quite a few photographs of these engines.

All of the minesweepers of the MSO class were constructed out of wood!!

There were MSO's and MSC's. The MSO's Were Ocean sweeps and the MSC's were Coastal sweeps.

I was just browsing Jane's American Fighting Ships of the 20th Century and came across this information on the Packard non-magnetic V12-diesel powered MSOs. I hope some of you find it interesting.

I was just browsing www.navsource.org and came across a bit more information on the Packard non-magnetic diesels used in MSO-421 (Agile) minesweeper.

Curiousity got the best of me today and I decided to take a look and see when the last of the originally Packard-powered U.S. Navy minesweepers were finally scrapped. I had read that some of these saw service in the Persian Gulf war and find it interesting that these were serving their government until so recently (though some engines were replaced by Waukasha diesels at some point). Much more info on the NavSource site listed above.

We are restoring a Korean War era wooden minesweeper. Take a look at www.stocktonhistoricalmaritimemuseum.org when you have chance. Send some of those Packard Marine engines our way.

The non megnetic marine diesels contains the aluminum, stainless steel, copper and brass. The are structures with
4 valve per cylinder and they use propulsion. There is use of different technology for powering these generators
without creating magnetic field.

I was a engineman on a minesweeper in the early 80s. Always hoped I would run across one for myself. As I remember they had about 600 bhp, at 3000 rpm. The sweepers had 4 main engines to two reduction gears. They were notorious for blowing head gaskets, which there was one for each cylinder.
