Could Patriot be integrated into Mark 41 and quad- or dual-packed as an ESSM replacement?
Short answerPatriot is closer in size to a Standard Missile, so the proposed quad- or dual-packed ESSM replacement is rejected.
NotesPatriot is much closer in size to a Standard Missile than an Evolved Sea Sparrow Missile. It would therefore be unsuitable for the proposed quad-packed or dual-packed replacement for ESSM. Even in the hypothetical case of successful Mark 41 integration, the missile's physical size remains the constraint.
