The Franklin was never equipped to handle the Trident II missile (D5), as stated in 1989. The D5 missile was too long and too large in diameter to fit in the Franklin’s 16 launcher tubes. Your reference to “…24 warheads…” is for an Ohio-class boat that had 24 missile tubes.
There were only 16 tubes on Franklin and she was built to carry the Polaris A3 missiles. During her first first back-fit she was converted to carry the Poseidon (C3) missile which was a MIRV-carrying missile that could carry at least 8 MK68 warheads per missile. During her second back-fit she was converted to carry the Trident I (C4), along with five other Franklin-class submarines. None of these submarines carried the Trident II (D5).
Also, at one point you refer to the Franklin “…as one of the Ohio-class submarines…”. That is not the case, as Franklin was the lead ship in the Franklin-class of submarines.
Finally, the reference to the Polaris (A3) missile to a MIRV is incorrect. Although the A3 was the first U.S. multiple-warhead missiles, it was not MIRV. The A3 carried three 200KT MK58 warheads that were all released at the same time and targeted to the same target.
