Post by a425coupleOne bit of info posted previously might provide further specifics.
(respects to original poster Keith Willshaw normally on smn)
A typical convoy left Seattle for Vladivostok in Jan 1944.
It was composed of 46 merchantmen (all 8-10K ton ships); built by
McCormack Ship Yards that were Soviet flagged and Soviet crewed.
Looks like it was officially the Moore drydock in the San Francisco
area, presumably part of the Moore McCormack line, the yard built
147.2 million dollars worth of ships for the USN and 346.8 million
dollars for the Maritime Commission from 1939 to 1945.
The detailed Maritime Commission listing either misses some
ships or costs, all are dry cargo types,
68 C2-S-B1 costing 247 million dollars, 2 C3 costing 5.6 million
dollars, 3 C3-M costing 5.7 million dollars, 6 R2-S-BV1, costing
28.25 million dollars,
6 C2-S-B1 attack cargo (AKA) ships for 26.8 million dollars,
3 C2-S-B1 transport attack (APA) ships for 16.3 million dollars,
11 C3-S-A2 transport attack (APA) ships for 60.5 million dollars.
3 C2-S1-A1 hospital ships (APH) for 19.8 million dollars.
The C2-S-B1 was 9,153 deadweight or 6,232 Gross register tons.
The R2-S-BV1 was refrigerated, 8,133 DWT, 6,178 GRT.
The C2-S-B1 AKA was 7,883 DWT, 6,100 GRT
The C2-S-B1 APA was 7,540 DWT, 6,100 GRT.
The C2-S1-A1 APH was 3,649 GRT, 8,300 GRT.
All the C2 types were roughly 450 by mostly 63 feet.
There are 2 C3 cargo types listed, either 12,468 DWT, 7,819 GRT
or 11,928 and 7,886, the C3-M was 12,115 DWT, 7,773 GRT.
It looks like the Maritime Commission had 79 C2-S1-B1 built during
the war, with some 36 of the 79 were built to end 1943, so Moore was
the major builder of the type. The R2-S-BV1 were built in 1945, the
civil C3 types in 1940 and 1941, the APA version from 1943 on.
The EC2 liberty ship was shorter and had less beam than the C2
designs but came in at 10,793 DWT, 7,187 GRT.
As stated the 46 ships would have had around a nominal 400,000
tons of cargo capacity.
In long tons shipments (I presume cargo ship tonnages) not
counting aircraft flown to the destinations,
Soviet Far East 8,244,000, Soviet Arctic (via Pacific)
452,000, North Russia 3,694,000, Persian Gulf 4,160,000
and Black Sea 681,000.
Soviet ships carried 3,401,000 long tons, US ships
transferred to Soviet registry 5,367,000 tons.
By protocol period, Pacific shipments, long tons
151,298 from 22 June to 30 September 1941
235,250 from 1 October 1941 to 30 June 1942
1,623,083 from 1 July 1942 to 30 June 1943
2,589,424 from 1 July 1943 to 30 June 1944
2,716,247 from 1 July 1944 to 12 May 1945
1,349,873 from 13 May to 2 September 1945.
Post by a425coupleSix of the 46 ships were loaded with ammunitions and small arms. Four of
the 46 ships were loaded with foodstuffs. Two of the 46 ships were loaded
by Dodge (presumably with trucks). One ship was loaded by Westinghouse
(presumably with communications gear).
20,000 tons of steel provided by U.S. Steel.
3,000 truck chassis, by Ford (the Soviets also assembled U.S. trucks from
parts).
No mention in the US Lend-Lease report of truck chassis, but that could
simply be trucks being shipped crated. 437,039 trucks and jeeps sent.
Post by a425couple3,000 truck differentials from Thornton Tandem Co.
2,000 tractors by Allis Chalmers Co. (agricultural and military use)
The US Lend-Lease report says 1,941 Truck-tractors, and 8,074
track laying tractors sent for the war.
Post by a425couple1,500 automotive batteries from the Price Battery Corp.
1,000 aircraft provided by the North American Aviation Co.
The US reports North American aircraft sent to the USSR (and arrived)
were 28 AT6-C (8 to North Russia, 20 via Abadan in the Persian Gulf),
and 54 AT6-F via the ALSIB air route, 733 B-25 via ALSIB, 5 to North
Russia, 124 via Abadan.
Losses of aircraft allocated to the USSR were 91 in the US, 59 in
Canada and Alaska, 310 via North Russia and 274 via Abadan.
Post by a425couple612 airplanes from the Douglas Aircraft Co.
Douglas aircraft arrivals in the USSR were 707 C-47 and 1,363 A-20
via ALSIB, 126 A-20 via North Russia, 1,419 A-20 via Abadan.
Post by a425couple600 trucks from Mack.
500 Allison aircraft engines.
500 half-tracks from Minneapolis Moline Co.
Total shipments of half tracks for the war were 1,158.
Post by a425couple400 airplanes from Bell Aircraft
Bell aircraft arrivals in the USSR 4,746 P-39, of these 2,618 via
ALSIB, 108 via North Russia and 2,020 via Abadan, along with
2,397 P-63 via ALSIB and 3 via North Russia.
Post by a425couple400 electric motors from Wagner Electric Co.
400 truck chassis by GM (see Ford above)
310 tons of ball bearings from the Fafnir Company.
200 aircraft provided by the U.S. Navy
US Navy types sent were 185 PBY/PBN.
Post by a425couple200 aircraft engines by Aeromarine
No aircraft engine manufacturer by this name in the
War Production Board report.
Post by a425couple100 tractor-trailer units by GM (trucks)
70 aircraft engines by Pratt & Whitney
---(so, I count 2,200+ aircraft on this convoy
--- from Seattle,
Which, if correct would amount to around a seventh of
the 14,797 USAAF and 185 USN aircraft sent, this total
does include 1,622 P-39, 49 P-40 and 88 P-63 on "British
account" but not any other aircraft for Britain redirected
to the USSR.
Sometimes the reports are in tons, rather than number of
aircraft, trucks etc.
It does not look like any aircraft were shipped via the Pacific
and generally weapons were not shipped via the Pacific, to
reduce the chances the Japanese would intervene.
