Anti-shipping Activity Messages (ASAM) include the geographic location and the reported descriptive accounts of specific hostile acts against ships, crews and passengers which include incidents of piracy, robbery, hi-jacking and kidnapping. Such reports may be useful for mariners traveling to or through active areas for recognition, prevention and avoidance of potential hostile activity. The ASAM Mobile app allows users to download all ASAMs to their mobile device and search, view, and query them independent of a data connection to increase maritime safety awareness. This app was developed by NGA in collaboration with Booz Allen Hamilton and contributors at GitHub (

I use this all the time

I pretty much check this application before leaving the house every day. It's like traffic reports, except pirates.
While this may sound over the top, it isn't. Consider math: number of times I have driven places after using this app: 971. Number of pirate incidents: 13 (but those were Pittsburg Pirates fans, which I don't think this app will cover until the next version?).
Either way, using the internet vetted premise of correlation = causation, this application has increased my safety by a ginormous amount.

Useful app!!

This app is very interesting to identify piracy on the seas and oceans. I like that it is updated from data pulls from servers.
