Sounds awesome and a great opportunity to expand your résumé. However, will it occur 'prior to' or inside the 'window' of your USNA (and other SAs') applications and will it impact other important activities that are important to USNA and the other SAs? For example, will you miss your sports season? Interrupt some good opportunities for leadership, etc.? If you do this as a sophomore or junior, then the timing is great. As a senior, it may be less interesting. But, in either instance, it should be fun and a great experience!
