    Which was a better all around, all purpose bomber for both land and maritime (torpedo bomber) operations?

    The SM 79 was considered by both Allied and Axis air-forces as being among the best torpedo-bombers ever built.

    Specifications:

    Savoia-Marchetti S.M.79 Sparviero

    Dimensions:
    Wing span: 69 ft 6 1/2 in (21.2 m)
    Length: 53 ft 1 3/4 in (16.2m)
    Height: 13 ft 5.5 in (4.1 m)

    Weights:
    Empty: 16,755 lb (7,600 kg)
    Operational: 24,192 lb (11,300 kg)

    Performance:
    Maximum Speed: 270 mph (434 km/h)
    Service Ceiling: 23,000 ft (7,000 m)
    Range: 1,243 miles (2,000 km)

    Powerplant:
    Powered by three 559 kW (750 hp) Alfa-Romeo 126 RC.34 radials. Later three Piaggio P.XI RC40 1,000 hp 14-cylinder radial. The twin-engined S.M. 79B variety. Romania built the 79JR under license with two 894 kW (1,200 hp) Junkers Jumo 211Da liquid-cooled engines.

    Armament:

    It carried a 12.7 mm Breda-SAFAT gun firing ahead from the roof of the cockpit humpback that enabled bullets to clear the nose propeller; a second firing to the rear from the hump; a third aimed down and to the rear from the gondola under the rear fuselage; and often a 7.7 mm firing from each beam window. this needing a crew of at least five. The bombardier occupied the gondola with his legs projecting down in two retractable tubes during the bombing run. Up to 1,000 kg (2,205 lb) of bombs were carried in an internal bay; alternatively two 450 mm (17.7 in) torpedoes could be hung externally

    For the torpedo bomber role, I'll go with the SM 79, more agile, slightly smaller and capable of absorb punishment. A torpedo bomber can't avoid AA fire.
    For the night bomber role, I'll go with the He 111, for the superior instrumentation and sight.
    For the day bomber role, it's difficult to say. The SM 79 was not considered very succesful in that role, but the italians made the comparison not with the He 111, but with the Cant Z.1007, that, apart for agility, was superior in all respects.

    An SM 79 wiewed from HMS Liverpool.

    any day bomber in 1940 onwards would usually get shot down in numbers

    The He 111 was a versitle workhorse adaptable to any and every task the Luftwaffe threw at it. Had the SM 79 been used in the full length of WW 2 it too would have proven itself quite amazing in multi-role use more so than it actually was.

    The 111 bombed normally but was used to launch the A-5 which was a mini V-2 as well as V-1s and the remote-guided Hs 293 anti shipping missile. The He 111 was even produced with 2 ships pliced together in the He 111Z for glider towing duties.

    A lot comes down to personal preference since the pair were fairly well matched in capabilities. The SM 79 had a bit better performance. The He 111 could haul a lager bomb load. The SM 79 was probably better at torpedo attacks.

    ONLY because the He 111 was active over the full span of the war I'd pick it and that's a poor reason since these planes tare tied in my view.

    Didn't the SM.79 carry a heavier bomb load?

    The normal internal bomb load is similar (1200 kg), but the Z.1007 had a more efficient storage-release system. The max. total bomb load of the Z.1007 was superior of about 1000 kg to that of the SM 79.

    Kiwimac's source said, "It also was a trimotor, powered by 1,000 hp Piaggio radials, and it carried four machine guns for self-defence as well as up to 2,000 kg (4,410 lb) of bombs or two torpedoes."

    You are saying the Cant Z.1007 could carry another 1,000kg (2,200lbs) which is 6,400lbs total or is Kiwimac's source incorrect?

    the source seems about correct to me. It says:
    "When Italy joined the war in 1940 its air force had nearly 1,000 bombers, of which well over half were Savoia-Marchetti S.M.79 Sparviero (Hawk) medium bombers. These trimotors, were thought by many to be among the best land-based torpedo bombers of the war. They could carry 1,250 kg (2,750 lb) of bombs internally or two torpedoes. Also active as a medium bomber around the Mediterranean and on anti-ship duties was the Cant Z.1007bis Alcione (Kingfisher) ,production of which began in 1939. It also was a trimotor, powered by 1,000 hp Piaggio radials, and it carried four machine guns for self-defence as well as up to 2,000 kg (4,410 lb) of bombs or two torpedoes."

    So the source give a 750 kg more load to the Z.1007.
    It's ever difficult to talk about the max. bomb load of a bomber, since it vary with the lenght of the mission (and the lenght of the airstrip). But the SM 79 normally carried only it's internal load (1200 kg), since the for Z.1007 is normal to carry 4 more 200 or 250 kg bombs under the wings.

    Dogwalker, the sources I have seen put the Cant Z.1007's maximum ordinance load at 2,646 lbs of bombs or 2 17.7-inch torpedoes. Thus my question.

    For example - Commando Supremo

    Both SM 79 and Z.1007 could carry various types of bombs, but the typical load was of 5 250 kg bombs (1250 kg internally).
    Both two could carry (alternatively) two 450mm torpedoes (875 kg each 1750 kg total).
    Both two had the possibility to carry bombs externally, under the wings, but only the Z.1007, operating from the same airstrips, used it extensively.

    Is that because you think it is better or because it is Italian...

    Anyway both were good and I agree with Dogwalker's assessment. For torpedo operation I would take the SM-79, for night bombing the He-111 and for day bombing I would probably take the He-111 because of it's better bomb sight.

    Bit of both. Dont forget the SM.79 had 3 radials and the He-111 2 inlines, making it more likely for the SM.79 to absorb more damage in that department...

    I have done some reading since this thread appeared and I have seen it mentioned several times that the SM.79 could absorb a lot of damage and still make it back to base.

    I'm reading about torpedoes as well and much to my surprise, the Italians may have had the best torpedoes of the war, or at least superior to the German and American ones. I don't know about the British or Japanes ones.

    The Germans apparently preferred using Italian torpedoes for aerial drops and the Americans studied the Italian torpedo design to improve theirs.

    I think the Japs had good torpedos.

    Anyone know anything about the British torpedos (besides the fact that when compared to the Italian ones, it was like a comparison of their crotch sausages - smaller but somehow still able to get the job done).

    Picture of 2nd Lieutenant Dalmazio Corradini illustrating the supremacy of Italian torpedoes vis a vis the British.
