Are the USS Arizona and RMS Titanic Considered the Same Type of Memorial?

In conjunction with the 100th anniversary of the sinking of the Titanic yesterday. From Yahoo! Answers.

Someone wrote them asking this question.

THE ANSWER: Both are considered grave sites, but not the same type of memorial. The Arizona is a war memorial and the Titanic is to civilians.

You can still see the wreck of the Arizona in the shallow waters of Pearl Harbor, but the Titanic is much too deep to be seen.

The Arizona is a war grave. On April 15, 2012, the Titanic became a UNESCO Protected Heritage Site.
