The USACE will NOT sacrifice any old ships during their current project of rebuilding the 1880s Oswego west pier breakwall, using concrete dolosse instead to avoid depleting the pool of potential museum ships!

They're trucking these ~20 ton monsters a long way (~100 miles), someone must not have read the part about the concrete casting plants usually being built close to where the dolosse will be used...
