USS Yorktown

Keeping the ship alive

The Bureau of Ships damage report follows Yorktown through bombing damage, controlled fires, aerial torpedo damage and severe listing. Her loss was not one uninterrupted moment of destruction. Damage-control and salvage efforts are central to the account. M18

The salvage attempt

The submarine attack that also struck Hammann interrupted salvage. Yorktown finally capsized on 7 June. The sequence matters when assessing both the human effort and the operational consequences. M18

The machinery behind a usable flight deck

A bomb damaged the boiler uptakes, the passages carrying exhaust from the boilers. Yorktown lost steam and stopped. Repairing the flight-deck opening therefore solved only one part of the problem: engineers also had to restore propulsion. The technical report records the ship recovering the ability to make about twenty knots before the later aerial-torpedo attack disabled her again. M18

Electrical distribution was another vulnerability. After the torpedo hits, the emergency diesel started but power could not be restored through the ship. A running generator alone was insufficient if the electricity could not reach the equipment that needed it. M18

During salvage, men removed weight, pumped and counterflooded to reduce the list. After the submarine attack the ship leaned less but sat deeper in the water. That is a useful distinction between balance and buoyancy: a more upright damaged ship was not necessarily a safer one. M18

Reading the damage report

Records had been lost. The report relies on accounts reconstructed by officers, a limitation that should remain attached to precise details extracted from it. Technical expertise does not make a report an independent eyewitness to every event.

Selected original-page scans have been inspected, including the opening account and a damage page. The retained extract does not establish the cover publication date or include every plate.

Her place in the larger story

The loss of Yorktown was part of the real American cost at Midway. A scenario in which all three American carriers are lost adds Enterprise and Hornet to that baseline; it must not count Yorktown twice.

Read what Midway changed and the alternative Japanese victory to follow those consequences. Earlier service, fuller equipment specifications and individual crew accounts remain profile research priorities.

Bombs and torpedoes at Midway

The weapons recorded in American and Japanese carrier sorties, and what their expenditure can tell us.

Douglas SBD Dauntless

The scout and dive bomber, its two-person crew and the bomb loads actually flown from Enterprise.

USS Hammann

Yorktown’s escort and salvage assistant, lost while helping the damaged carrier after Midway’s air attacks.

Hiryū

The Japanese carrier that launched two counterattacks after the morning disaster at Midway.

USS Hornet

The carrier whose separated morning strike brought disaster to Torpedo Eight, and whose surviving air group kept fighting.

Nakajima B5N2 Kate

The three-seat Japanese carrier attack aircraft, its crew and its documented torpedo mission against Yorktown.

Mark 13 aerial torpedo

The carrier’s island strike, the rapid spread of fire and the evacuation of her surviving crew.

Type 91 aerial torpedo

The modification recorded in Hiryū’s Midway attack, checked against the postwar naval technical investigation.

Aichi D3A1 Val

The Japanese dive bomber that struck Midway and carried Hiryū’s first counterattack to Yorktown.

M18Yorktown’s damage report

Technical report · third-party scan extract

Passage: PDF pp.4–6 / printed pp.1–3, paragraphs 1–16; damage plate on PDF p.17

The sequence of damage, recovery, interrupted salvage and loss of Yorktown. Fuel precautions, flight-deck repair, boiler recovery, loss of power and abandonment.

Checked: PDF pages 4 and 17 visually inspected; other text selectively examined. PDF pp.4–5 rendered and visually rechecked on 18 October 2026 for Hiryū Fights Back. PDF p.6 / printed p.3 visually inspected for towing, salvage, the submarine attack and final loss. Supporting-ship update: PDF p.6 visually rechecked for Vireo’s tow and Hammann’s salvage assistance.

Limits: Relies on officers’ reconstructed recollections after records were lost. Cover publication date and complete plate set are absent from the retained extract. Draws on the captain’s submissions, so is not independent corroboration of M04. Its 1645 torpedo-hit time differs from M04’s approximately 1620, and its 23-degree abandonment list differs from M04’s 26 degrees. The paragraph 10 elapsed-time arithmetic is inconsistent; no exact repair duration is inferred from it. The post-Hammann underwater explosion is tentatively attributed to depth charges, whereas M44 leaves the cause unresolved. The smaller list after the later attack did not mean improved overall buoyancy.
