Ahh well… usually BB traveled with DD and CV traveled mostly with CA . Say at Layte gulf you had like 1-2 battleships along with 8-12 destroyers ( about a 6 to one).
The carriers were escorted by a ring of ships: below is what Nagumo had at midway…
FIRST CARRIER STRIKING FORCE (1st Air Fleet), VADM Chuichi Nagumo
Carrier Group, VADM Nagumo
CarDiv 1
CV Akagi (flagship, Akagi) 21 Zero fighters, 21 dive bombers, 21 torpedo bombers (Sunk)
CV Kaga (Kaga) 21 Zero fighters, 21 dive bombers, 30 torpedo bombers (Sunk)
CarDiv 2 – RADM Tamon Yamaguchi
CV Hiryu (flagship, Hiryu) 21 Zero fighters, 21 dive bombers, 21 torpedo bombers (Sunk)
CV Soryu (Hiryu) 21 Zero fighters, 21 dive bombers, 21 torpedo bombers (Sunk)
Support Group – RADM Hiroaki Abe CruDiv 8
CA Tone (flagship, Tone)
CA Chikuma (Tone)
2nd Section, BatDiv 3 –
BB Haruna (Kongo)
BB Kirishima (Kongo)
Screen (DesRon 10) – RADM Susumu Kimura
CL Nagara (flagship, Nagara)
DesDiv 4 – 4 DDs
DesDiv 10 – 3 DDs
DesDiv 17 – 4 DDs
Supply Group – 5 oilers, 1 DD
At Leyte gulf the japanese had:
5 BB (Yamato, Musashi (S), Nagato, Kongo, Haruna)
10 CA (Atago (S), Takao, Chokai (S), Maya (S), Myoko, Haguro, Kumano,
Suzuya (S), Chikuma (S), Tone)
2 CL (Noshiro (S), Yahagi)
15 DD (Shimakaze, Hayashimo (S), Akashimo, Kishinami, Okinami, Naganami, Asashimo,
Fujinami (S), Hamanami, Kiyoshimo, Nowaki (S), Urakaze, Isokaze, Hamakaze, Yukikaze)
It may be hard to extrapolate some idea about your question but its clear that the ratio of suporting ships was allways in excess of the primary warships. perhaps you have a good idea with this… propose some idea lets take a look.
