It was carrying three GLONASS (Russian GPS, sometimes combined with traditional GPS for improved accuracy, fix time etc - e.g. iPhone 4S/5) satellites. The loss of another three in 2010 was estimated to cost up to $160 million[1]. Expensive, but presumably nothing crippling in the scheme of things ($4.6 billion spent on the program from 2001-2011 [1])
Stereotypically satellite launch insurance is a comsat thing.
That doesn't mean there's no insurance involved in the whole process. Somebody will pay out third party liability claims, for example, either .gov or some insurance co or more likely a mixture of them. But specifically launch loss insurance is something "mostly" found with commercial comsats. Note its just stereotypical. Maybe this is the first navsat I've ever heard of with launch insurance.
