Narrative:

At the time of this event I was working the local position at stl. I cleared an E145 to land on runway 12L. When he was very short final I saw that his landing gear was not down and immediately sent him around. The aircraft gear was up; but the nosewheel doors were open. After discussing the event with the copilot he informed me that all of his equipment in the cockpit showed the gear down and locked. The copilot also informed me about an event some days ago with an E135 with the exact gear problem. When I saw the picture of the E135 it looked exactly like the E145 did at stl with no gear; but the nosewheel doors open. I am filing this report because I'm concerned that the embraer may have a serious problem with its landing gear system. As a controller with over 16 yrs of experience I have never heard of an air carrier landing gear up without the pilot knowing about the problem before coming in to land. For this to have happened twice in recent days is very concerning.
