Może to zdjęcie w czymś pomoże, opisane jest jako uszkodzenia po trafieniu Nevady 250 kg bombą zrzuconą przez D3A1 z Hiryu.

W Casablance, ludzie którzy przeprowadzili analizę trafień Jean Bart uznali że spowodowały je bomby dwukrotnie silniejsze niż faktycznie użyte. To taki przykład, ale cos podobnego miało miejsce wielokrotnie. Nie zamierzam niczego negować, ale wydaje mi się że wszelkiego wyrocznie należy chyba traktować zgodnie z nazwą, czyli co najmniej z bardzo dużą ostrożnością – zdaje się zresztą, że tak jak wszystkie raporty wojenne (nie dalej jak kilka dni temu, po raz kolejny miałem okazję się o tym przekonać).wyrocznią są raporty ludzi, którzy naprawiali uszkodzenia, a jeszcze większą te pochodzące od osób, co je analizowali
- Na zdjęciu widzimy rzeczywiście trafienie bombą 250 kg, o czym świadczy rozerwany pokład górny, który zainicjował bombę (32 mm MS + 50 mm teaku starczy). Zniszczeniu uległy dwa przedziały i poszycie wraz z pancerzem pokładu górnego i drugiego.dessire_62 pisze:Ciekawa dyskusja.

Ale tu pytanie: co w przypadku Nevady oznacza quarterdeck?She was down severed feet by the head from a torpedo in her bow and a bomb in the quarterdeck.
Smitha uważam za bardzo kompetentnego autora - bardzo jestem ciekaw zdania Kolegów na temat powyższej analizy.This bomb caused extensive structural damage on the battleship's upper, main and second decks, forward of No. 1 gun turret. It left an entrance hole in the upper deck at frame 25 1/2 about 3ft from the port waterway, which was similar in appearance to the holes made by bombs one and two. The main and upper decks, however, were blown up and fractured nearly all the way across at about frame 27 with extensive damage forward and aft on these levels; and there was also a long split in the port aide of the upper deck.
So great was the damage that at first it was thought that a larger bomb than a 250kg had been used or that two bombs hit in the same spot, but this was later shown not to have been the case. Careful examination revealed no evidence of more than one bomb explosion, but did show the bomb was the same type as bombs one and two. This bomb entered the upper deck and penetrated to the second deck, before striking the ship's armour and ricocheting off it. The explosion took place just beneath the main deck and only two fragments pierced the shell below the main deck (both on the starboard side) but the blown-up portion of the main deck was riddled with fragments. The blast damage was consistent with that expected from a 30kg charge in an armour-piercing bomb, with better fragmentation.
The split in the deck was attributed to gasoline vapour venting via a bomb hole, which had filled a storage space, exploding as flames from one of numerous fires reached it. Bulkhead 8 1/2 was torn loose at the bottom and blown aft and a door in bulkhead 5, which opened into the gasoline measuring room A-1-1-A, was blown forward. The trunk on the centerline between frames 13 and 14 was badly crushed and torn from the deck. Adjacent partition bulkheads in A-1-8-L were blown forward and aft. This explosion also caused a bulge in the upper deck and a long split in the deck.
Excluding the effects of this gasoline vapour explosion and the two-day fire in this part of the ship, the structural damage caused by this bomb was much less impressive than at first sight. Taking into account the confined space in which the explosion took place, and the weakness of the upper deck with two skylights and a hatch in approximately the same traverse line, it was concluded that a single 250kg bomb would account for this damage.
The second deck consisted of four layers:
80lb special treatment steel. 50lb special treatment steel, 50lb nickled steel and 50lb medium steel. It was dished downward maximum of 4 1/2in at the point of bomb ricochet, a distortion due to impact and increased by blast effect. This caused two stanchions beneath it to buckle. All bulkheads in the junior officers' quarters A-224-L were completely demolished, bulkhead 11 1/2 was bulged forward and so was bulkhead 9 to a lesser damage. All four sides of trunk A-80-T were dished inward but this was probably caused by the vapour explosion mentioned earlier. Bulkhead 30 was blown out at each side boundary and buckled throughout. The first four port side compartments in the warrant officers' quarters, A-240-L, abaft bulkhead 30 were demolished and many partitions in this space were distorted. Blast damage on the second deck stopped at bulkhead 50 which was only bulged aft slightly on the port side.
There were two fragment holes in the shell plating to starboard on the second deck level. The deck was deeply scored for about 6ft inboard from the ricochet mark. The chain pipes and capstain shafts were gouged by fragments. Further fragment damage was probably obliterated by the subsequent gasoline explosion which demolished bulkheads in the vicinity. The main deck was torn open along frame 27 for about 20ft on each side of the centreline and the edges of this split were blown sharply upward. Many fragments pierced it from below, especially on the port side. Blast damage on the main deck was much less extensive than on second deck. The after bulkhead of the wardroom was ruptured on each side and a moderate amount of blast distortion was caused to compartments in A-140-L. The forward bulkhead of the wardroom was bulged and wrinkled but there appeared to have been no bomb blast forward of it.
The upper deck fractured all the way across between the stringer plates with longitudinal tears along the stringer seams across to the wardroom skylights and the hatch. The anchor windlass shafts pulled apart at the couplings between the main and upper decks. The capstans were blown upwards and struck the outboard guns of No. 1 turret with such violence that the elevating screw was slightly bent and the supports of the elevating screw tailing box were sheared. A portion of the deck to starboard was blown upward at an angle of about 60 degrees, carrying with it the attached electric deck winch; this was partly pushed back into place and the winch removed. The corresponding portion of the deck on the port side was bent downwards. This seemed strange, even when considering the weight of the winch, but the report added that bomb blast often produces peculiar effects because of multiple reflections of the blast wave which always occured.
Czy na pewno? Czy mogę prosić o źródło tej informacji?Maciej3 pisze:250 kg bomby Vali były bombami burzącymi.
Zdecydowanie NIE na pewno. Jeśli chodzi o samoloty to wszelka moja pisanina jest obarczona dużym potencjalnym błędem. Te latające straszydła obchodzą mnie jako cele ewentualnie jakie poczyniły szkody.Czy na pewno? Czy mogę prosić o źródło tej informacji?

Dziwne by to było o tyle, że celem nurkowców drugiej fali miały być okręty, a Japończycy posiadali przecież bomby 250 kg (Typ 99 Nr 25), które w angielskojęzycznych publikacjach określane są jako semi armour-piercing.Maciej3 pisze:Zdecydowanie NIE na pewno. (...) Bomby burzące z dużym znakiem zapytania.
To wiele tłumaczy. Jest to bomba półprzeciwpancerna - czyli takie coś pomiędzy burzącą a przeciwpancerną.które w angielskojęzycznych publikacjach określane są jako semi armour-piercing.

Przepraszam, poprawka za Friedmanem - ten pokład składał się nie z trzech lecz CZTERECH warstw o tej łącznej grubości - czyli jeszcze gorzej.
