How many F-18 fighter jets does the American military have?

Hi, I would like to know how many F-18 combat aircraft does the main military force of the United States of America have. I know that they are operated by the United States Navy and Marine Corps. I would like to know what aircraft models do they have and what weapons do they carry. These are fighter jets are carrier based aircraft that are typically designed to land and take off on both land and aircraft carriers.
