Multiple Jumps to Get to Coronado NASNI - Broken Certificate

From a search on Google for "Coronado NASNI" (Naval Air Station North Island), it takes three jumps to get you to the current web site for NASNI. The Google search for Coronado NASNI brings you to the site www.nasni.navy.mil. Clicking www.nasni.navy.mil brings you to a web page which says "www.nasni.navy.mil URL has changed to www.nbc.navy.mil

When you get to http://www.nbc.navy.mil/, you get a similar forwarding message saying,

"This site has moved. You will be automatically redirected to its new location in 10 seconds. If you aren't forwarded to the new page, click here. - https://www.cnic.navy.mil/coronado"

When you click on https://www.cnic.navy.mil/coronado, it brings you to an site with an invalid security certificate which reads
