Paul Gustard insists England will adopt a "hunting mentality" to drive their pursuit of an unprecedented third successive Six Nations title.
Eddie Jones' men are favourites to retain the crown when their championship opens against Italy in Rome on Sunday week, but Ireland and Scotland are expected to mount strong challenges.
Rather than defending the title, Gustard insists England will be best served by taking an offensive approach.
"We want a hunting mentality in this Six Nations. We want to go after teams, stamp our authority on them and dominate them," defence coach Gustard said.
"We want to hunt teams in every aspect. We want to go after them, put them under pressure and strive to be the best in the world. That starts with a successful performance against Italy.
"The Six Nations is a great competition. There are five other good teams in there but we've been the best team over the last two years.
"We want to win the Six Nations but we've seen some good strides made by Ireland, Wales and Scotland over the autumn.
"They've had good press on the back of that, but we're hungry to make it three from three."
England are currently on a week-long training camp in Vilamoura, Portugal, ahead of the tournament.
Gustard has previously outlined his aspiration of giving England the meanest defence on the world stage, and last autumn strides were taken in that direction when they leaked only three tries against Argentina, Australia and Samoa.
Since November the former Saracens back row has spent a spell at Super Rugby team the Melbourne Rebels to sharpen his coaching skills.
"Statistically we had the best defence in 2017. We had a successful autumn and we want to look at different things," Gustard said.
"I then went away to Melbourne to get some more coaching experience, trying some new things that I want to try to implement for us.
"There will be small tweaks, small additions and nuances with the overall goal of trying to get better.
"It was more about the coaching experience that I had there, coaching different players and practising different ideas that I had.
"I wanted to look at different skills and drills and philosophies to make our defence better."
