Estimating a US destroyer's helicopter ordnance

Guessed ammunition weights illustrate how paired helicopters, weapons and sonobuoys affect a destroyer's storage requirements.

Question

How much ordnance does a US Navy destroyer carry for its helicopters, measured by weight?

Short answer

No verified total is given. An 8 to 12-ton guess is considered low, particularly when supporting two helicopters, and exact holdings are withheld.

Notes

No confirmed tonnage is supplied. Dan labels his estimate as a guess, while the initial figure of 8 to 12 tons is judged too low. Supporting two helicopters increases the requirement beyond a calculation for one aircraft. Torpedoes, depth charges, missiles and sonobuoys contribute different weights and storage volumes. Dense ammunition can occupy relatively little space, while sonobuoys introduce a larger volume requirement. An exact figure is withheld because of a stated classification concern, leaving the quantities and weight conversions unresolved.
