A connected aircraft profile

Curtiss SB2C Helldiver

The Helldiver carried the dive-bomber role into the later Pacific war. In the approach to Yamato’s force, a bomber’s radar also helped the attackers find their target.

The photograph is dated 1945; the particular sortie and crew are not identified. VB-82’s 7 April report records both SB2C-4 and SB2C-4E aircraft.

After the Dauntless

The Helldiver was designed to replace earlier carrier scout bombers, including the SBD Dauntless familiar from Midway. Its design combined two seats, folding wings for carrier storage and an internal bomb bay. Serious development and handling problems delayed its introduction. The Smithsonian’s collection history dates its first combat sorties to November 1943. YT-Y19

The same history describes a faster aircraft with greater ordnance capacity than the Dauntless, but one that demanded intensive training. By the later Pacific campaigns, Helldivers formed part of carrier groups alongside fighters and torpedo aircraft. This was a change in the equipment available, not a guarantee that every sortie would succeed.

The aircraft in this strike

VB-82’s own report records eleven Helldivers launched on 7 April 1945, with nine attacking. Its aircraft table lists both SB2C-4 and SB2C-4E variants. This is more specific than the accompanying torpedo squadron’s table, which describes the eleven bombers together as SB2C-4Es. YT-Y20 YT-Y18

The bombing squadron records a normal load of two 1,000-pound semi-armour-piercing AN-M59 bombs, with one aircraft also carrying a 250-pound general-purpose AN-M57. These were different weapons from the Avengers’ Mark 13 torpedoes. YT-Y20

Finding ships beneath cloud

The torpedo squadron’s narrative credits a radar-equipped bombing aircraft with contact at twenty-five miles. VB-82’s own account identifies the crew: Lieutenant Commander Hugh Wood Jr flew the aircraft, and H. H. Reed operated its radar. Their contact helped the formation find the Japanese ships beneath cloud. YT-Y18 YT-Y20

Cloud also shaped the bombing. Four aircraft attacked the battleship; five attacked ships described as cruisers or destroyers. The attack table calls the technique a glide, with releases between 2,500 and 1,000 feet. The narrative explains that where a pilot emerged from cloud affected which ship he could attack. YT-Y20

The aircraft that did not return

Ten aircraft returned. The report lists Ensign Jack Carl Fuller and his gunner Charles Williams Jr as missing, and three other aircraft as damaged but repairable aboard. Its account of parachutes does not identify their occupants. These entries record what the squadron knew when it completed the report. YT-Y20

What the crews could establish

The squadron claimed hits on Yamato, but its own diagram warns that several observers might have seen the same explosion. The camera fitted for damage assessment was aboard the lost aircraft. The claims therefore cannot simply be added together or treated as a complete survey of the battleship’s damage. YT-Y20

Keep the variants separate

The Smithsonian’s preserved aircraft is an SB2C-5, accepted after this battle. Its collection history explains the wider family, but its dimensions and equipment are not used here as an exact specification for Bennington’s SB2C-4 and SB2C-4E aircraft. YT-Y19

YT-Y20Bennington VB-82 Aircraft Action Report No. 37

Original wartime squadron action report · digitised scan

Passage: Report 37, PDF pp.1–6 and 9: aircraft, loads, radar contact, attacks, losses and uncertainty in hit claims

Mixed SB2C-4 and SB2C-4E aircraft; eleven launched and nine attacking; recorded bomb loads; radar contact by Wood and Reed; attacks shaped by cloud; one missing aircraft, its two missing crew and three repairable aircraft; explicit uncertainty about duplicate hit observations.

Checked: All nine rendered PDF pages visually inspected on 20 October 2026. Complete scan retained with SHA-256 cf8952c735396cef89c5d367823c700146f4218f8f8315699b5a5c495d867169. Tables checked against narrative and hit diagram. The earlier catalogue lead NDL4003169 is report 66 for VF-82 Hellcats, not VB-82.

Limits: A participant report compiled after the action, not a Japanese damage survey. Enemy ship identifications, hit allocation and comparisons with the March Kure attack reflect contemporary interpretations. Its diagram explicitly warns of duplicate observations. Missing status is as recorded in this report; parachutes seen were not identified. Eleven launched is not eleven confirmed attacks.

YT-Y18VT-82’s attack on the Japanese surface force

Contemporary aircraft action report · scanned archival copy

Passage: Report 35-45, PDF pp.1 and 5: supporting SB2C-4E aircraft and radar contact during approach

TBM-3 identity; ten launched and nine attacking; Mark 13 torpedoes and twelve-foot depth setting; auxiliary tanks, reduced crews and target selection; damage and return; supporting SB2C-4Es and radar contact.

Checked: All eight PDF images visually inspected on 20 October 2026. Own-aircraft and supporting-aircraft tables, damage table, attack table, formation diagram, crew list, narrative and approval line checked. Public scan downloaded from Wikimedia Commons; Commons catalogue attributes it to NDL USB-06R04:0141–0148 and the NARA USSBS collection.

Limits: An American squadron account, not a Japanese damage survey. Target identifications include two cruisers where the Japanese force record identifies one. Hit and sinking claims are not independently confirmed. The damage sheet is numbered 34-45 while the cover and remaining report sheets read 35-45. Its damage table and narrative differ on gun calibre and injury severity; no exact calibre or medical grading is adopted. The eleven SB2C-4Es are supporting aircraft, not an own-squadron bombing or loss return. The ASH-equipped VB is not identified by individual aircraft or crew. Reported times retain the form’s zone convention.

YT-Y19Curtiss Helldiver: aircraft family and preserved SB2C-5

Later institutional collection history

Passage: Museum collection history: development, first combat, folding wings and differences between variants

Scout/dive-bomber role; two-seat design, folding wings and internal bomb bay; development difficulties; first combat in November 1943; distinction between SB2C-4 and preserved SB2C-5.

Checked: Complete collection-page HTML downloaded and its historical narrative read on 20 October 2026, after browser fetch failed. The retained aircraft’s acceptance date and variant description checked separately from general type history.

Limits: A modern museum account, not a wartime sortie report. The preserved SB2C-5 was accepted on 19 May 1945 and did not fight in the Yamato attack. Its individual specifications are not assigned to VB-82’s SB2C-4 and SB2C-4E aircraft. Their loads and sortie details are now checked separately against original report YT-Y20.
