Derelict/Juggernaut - Bio-Mechanoid

I believe the Space Jockey vessel known as the Derelict/Juggernaut is... ...A female symbiotic bio-mechanical lifeform, that is/was bred by the Space Jockey's for the purpose of deploying Alien/Xenomorph eggs where needed. I believe they are living creatures because it would make more sense to grow or breed your technology than to construct it. I believe they are female for 3 obvious reasons, plus another - their underbelly section is essentially a bio-mechanical surrogate womb used to store and protect Alien/Xenomorph eggs. I believe they are symbiotic, requiring a pilot to fully function. Without a pilot they enter a form of hibernation where they remain inactive put continue to support any eggs within their womb. Of course this begs the question, where/what are the males - another type of vessel we haven't seen yet, or maybe (and more disturbingly) the Space Jockeys.
