Fireboats and the protection of naval ports

Light replenishment oilers are discussed as smaller ships that could be risked in more dangerous areas than the massive John Lewis class. The support-ship list also includes hospital ships, bulk fuel tankers, and fireboats. Naval ports concentrate expensive ships alongside fuel, paint, and other flammable material. A purpose-built fireboat can approach a burning warship and supply its fire mains while accepting risks beyond an ordinary harbor craft's role. The five proposed fireboats prompt concern about whether that number would protect enough of the fleet's port infrastructure.
