Please answer the given financial question based on the context.
Context: 2015 compared to 2014 mfc 2019s net sales in 2015 decreased $ 322 million , or 5% ( 5 % ) , compared to the same period in 2014 . the decrease was attributable to lower net sales of approximately $ 345 million for air and missile defense programs due to fewer deliveries ( primarily pac-3 ) and lower volume ( primarily thaad ) ; and approximately $ 85 million for tactical missile programs due to fewer deliveries ( primarily guided multiple launch rocket system ( gmlrs ) ) and joint air-to-surface standoff missile , partially offset by increased deliveries for hellfire . these decreases were partially offset by higher net sales of approximately $ 55 million for energy solutions programs due to increased volume . mfc 2019s operating profit in 2015 decreased $ 62 million , or 5% ( 5 % ) , compared to 2014 . the decrease was attributable to lower operating profit of approximately $ 100 million for fire control programs due primarily to lower risk retirements ( primarily lantirn and sniper ) ; and approximately $ 65 million for tactical missile programs due to lower risk retirements ( primarily hellfire and gmlrs ) and fewer deliveries . these decreases were partially offset by higher operating profit of approximately $ 75 million for air and missile defense programs due to increased risk retirements ( primarily thaad ) . adjustments not related to volume , including net profit booking rate adjustments and other matters , were approximately $ 60 million lower in 2015 compared to 2014 . backlog backlog decreased in 2016 compared to 2015 primarily due to lower orders on pac-3 , hellfire , and jassm . backlog increased in 2015 compared to 2014 primarily due to higher orders on pac-3 , lantirn/sniper and certain tactical missile programs , partially offset by lower orders on thaad . trends we expect mfc 2019s net sales to increase in the mid-single digit percentage range in 2017 as compared to 2016 driven primarily by our air and missile defense programs . operating profit is expected to be flat or increase slightly . accordingly , operating profit margin is expected to decline from 2016 levels as a result of contract mix and fewer risk retirements in 2017 compared to 2016 . rotary and mission systems as previously described , on november 6 , 2015 , we acquired sikorsky and aligned the sikorsky business under our rms business segment . the 2015 results of the acquired sikorsky business have been included in our financial results from the november 6 , 2015 acquisition date through december 31 , 2015 . as a result , our consolidated operating results and rms business segment operating results for the year ended december 31 , 2015 do not reflect a full year of sikorsky operations . our rms business segment provides design , manufacture , service and support for a variety of military and civil helicopters , ship and submarine mission and combat systems ; mission systems and sensors for rotary and fixed-wing aircraft ; sea and land-based missile defense systems ; radar systems ; the littoral combat ship ( lcs ) ; simulation and training services ; and unmanned systems and technologies . in addition , rms supports the needs of government customers in cybersecurity and delivers communication and command and control capabilities through complex mission solutions for defense applications . rms 2019 major programs include black hawk and seahawk helicopters , aegis combat system ( aegis ) , lcs , space fence , advanced hawkeye radar system , tpq-53 radar system , ch-53k development helicopter , and vh-92a helicopter program . rms 2019 operating results included the following ( in millions ) : .
||2016|2015|2014|
|net sales|$ 13462|$ 9091|$ 8732|
|operating profit|906|844|936|
|operating margin|6.7% ( 6.7 % )|9.3% ( 9.3 % )|10.7% ( 10.7 % )|
|backlog atyear-end|$ 28400|$ 30100|$ 13300|
2016 compared to 2015 rms 2019 net sales in 2016 increased $ 4.4 billion , or 48% ( 48 % ) , compared to 2015 . the increase was primarily attributable to higher net sales of approximately $ 4.6 billion from sikorsky , which was acquired on november 6 , 2015 . net sales for 2015 include sikorsky 2019s results subsequent to the acquisition date , net of certain revenue adjustments required to account for the acquisition of this business . this increase was partially offset by lower net sales of approximately $ 70 million for training .
Question: what were average net sales for rms in millions between 2014 and 2016?
