The US carrier strike group headed toward Israel is heavily armed, but these ships could still be sailing into dangerous waters

• A US Navy carrier strike group is heading for Israel after the deadly Hamas attacks on Saturday.
• These ships — which include the Navy's most advanced carrier — are heavily defended and well armed. 
• But they may be sailing into dangerous waters as Lebanon's Hezbollah becomes more involved. 

The US Navy dispatched a carrier strike group to waters near Israel after a brutal attack over the weekend by the Hamas militant group. The warships are well armed, but they may be entering a hostile environment, dangerous waters with foes who possess anti-ship missiles.
