In the last couple of weeks the US Navy has thinned most of the Arctic ice by 50-75%

They're using a new model. Here's the last image from the old thickness model:


And here's the one for the same date using the new model:

2. I'm not seeing any images in your OP.

4. The xxxnavy.mil website is using invalid security certificates, so the browser not loading graphics

That is why the graphics are not showing, at least in my firefox browser.

3. Do you have a link to the new model graphics? Did they go back to 2012?

5. Here's a link to the main page

The snapshot archive only goes back to 2014 when they started testing it. According to the old site, "As of 30 Sept 2017, ACNFS will be replaced by the Global Ocean Forecast System (GOFS 3.1). Daily Arctic and Antarctic ice products are available from the GOFS 3.1web page. The ACNFS webpage will remain in service for historical purposes but will not be updated with real-time ice forecast products."

And here's the link to the new model. You will have to click on the thickness snapshot archive and then go to the line that says run on 2017101612 valid 2017101700 to see the correct image
