Mobile Siphon Units, when placed around a player owned starbase with a moon harvesting laser or a reactor, will siphon off a portion of the moon minerals or reaction results that go towards the station's silos. They are designed to be secretly deployed near to a POS and will not alert the owner to the theft of materials nor will the stations guns automatically shoot at it, meaning that people who own POSs need to keep a watchful eye out for any of these things floating around. Like the Mobile Cynosural Inhibitor this is a one use item. One twist is that any pilot may access the hold so even the thieves aren't immune to theft. It only takes up 35 m³, takes 5 seconds to deploy and will last 30 days with a cargo hold of 900 m³ but needs to be between 30 and 50 km of the target, so CovOps ships can truly take advantage of these automated thieves.

• Requires Anchoring II to deploy.
• No criminal or suspect flags will be placed upon attacking the siphon.
• Will prioritize raw materiel over refined (cannot take alchemy output).
• Can only steal from one silo at a time and only the one at the end of a chain.
• Will take 60 raw or 30 processed items at a time.
• Players cannot put items into it.
• Multiple siphon units can be placed around the POS and will steal in order deployed.
• Have a waste factor of 10%, meaning that 10% of the items stolen are lost.
• Will only steal during a production cycle (once per hour).
• Can be manually targeted by station guns.
