Roberts argues that the focus on the Baltic was probably unimportant at the time the ships were designed, but was inflated later, after the disastrous Dardanelles Campaign.
Roberts mener, at tankerne om Østersøen formentlig havde ringe betydning på designtidspunktet, men at man flyttede fokus over på det senere, da kampagnen i Dardanellerne var endt som en fiasko.
