Brytyjskie
pancerniki typu N3 – miały być zbudowane w latach20-tych, z
wykorzystaniem brytyjskich doświadczeń pierwszowojennych. Byłyby
opotężne okręty, zapewne nie mające sobie równych w swoim czasie, nie
wyłączając współczesnych im projektów amerykańskich czy japońskich.
Niestety,nigdy nie zbudowane na skutek postanowień traktatu
waszyngtońskiego, stały się podstawąprojektu pancerników Nelson i
Rodney. Proponowane nazwy to Anson, Howe, Nelson i Rodney (lub St. Andrew, St.David, St. George i St. Patrick. Oto symulacja w springsharpie:
