We were not, these weapons (and medium range missiles) were banned under treaties, but Russia tore this up.
Is INF the treaty you are mentioning being ignored? Is Russia's announcement a direct response to the USA's? Disappointed that recent history hasn't been even mentioned in most reporting around the announcement -- it's a pretty shocking headline to wake up to without context.

No, the US had nuclear cruise missiles deployable on subs since the 1980s or possibly 1970s (I can't find a good date for introduction of the TLAM-N, only that development began 1972 and it was announced they would be transfered to storage in 1991 and they were retired between 2010 and 2013.)
What your source reports is a recommendation to introduce a new nuclear cruise missiles replacing the retired TLAM-N.
