when did seahawks go to super bowl

The Seattle Seahawks have been to the Super Bowl three times so far:

• February 5, 2006 – Super Bowl XL vs. Pittsburgh Steelers (first-ever Seahawks Super Bowl appearance)

• February 2, 2014 – Super Bowl XLVIII vs. Denver Broncos (Seattle’s first and only Super Bowl win, a 43–8 blowout)

• February 1, 2015 – Super Bowl XLIX vs. New England Patriots (the famous last‑minute Malcolm Butler interception game)

So if you’re just looking for when the Seahawks went to the Super Bowl: 2005 season (played Feb 2006), 2013 season (played Feb 2014), and 2014 season (played Feb 2015).
