aeronautics business segment 2019s results of operations discussion .the increase in our consolidated net adjustments for 2011 as compared to 2010 primarily was due to an increase in profit booking rate adjustments at our is&gs and aeronautics business segments .aeronautics our aeronautics business segment is engaged in the research , design , development , manufacture , integration , sustainment , support , and upgrade of advanced military aircraft , including combat and air mobility aircraft , unmanned air vehicles , and related technologies .aeronautics 2019 major programs include the f-35 lightning ii joint strike fighter , f-22 raptor , f-16 fighting falcon , c-130 hercules , and the c-5m super galaxy .aeronautics 2019 operating results included the following ( in millions ) : .
[['', '2012', '2011', '2010'], ['net sales', '$ 14953', '$ 14362', '$ 13109'], ['operating profit', '1699', '1630', '1498'], ['operating margins', '11.4% ( 11.4 % )', '11.3% ( 11.3 % )', '11.4% ( 11.4 % )'], ['backlog at year-end', '30100', '30500', '27500']]
2012 compared to 2011 aeronautics 2019 net sales for 2012 increased $ 591 million , or 4% ( 4 % ) , compared to 2011 .the increase was attributable to higher net sales of approximately $ 745 million from f-35 lrip contracts principally due to increased production volume ; about $ 285 million from f-16 programs primarily due to higher aircraft deliveries ( 37 f-16 aircraft delivered in 2012 compared to 22 in 2011 ) partially offset by lower volume on sustainment activities due to the completion of modification programs for certain international customers ; and approximately $ 140 million from c-5 programs due to higher aircraft deliveries ( four c-5m aircraft delivered in 2012 compared to two in 2011 ) .partially offsetting the increases were lower net sales of approximately $ 365 million from decreased production volume and lower risk retirements on the f-22 program as final aircraft deliveries were completed in the second quarter of 2012 ; approximately $ 110 million from the f-35 development contract primarily due to the inception-to-date effect of reducing the profit booking rate in the second quarter of 2012 and to a lesser extent lower volume ; and about $ 95 million from a decrease in volume on other sustainment activities partially offset by various other aeronautics programs due to higher volume .net sales for c-130 programs were comparable to 2011 as a decline in sustainment activities largely was offset by increased aircraft deliveries .aeronautics 2019 operating profit for 2012 increased $ 69 million , or 4% ( 4 % ) , compared to 2011 .the increase was attributable to higher operating profit of approximately $ 105 million from c-130 programs due to an increase in risk retirements ; about $ 50 million from f-16 programs due to higher aircraft deliveries partially offset by a decline in risk retirements ; approximately $ 50 million from f-35 lrip contracts due to increased production volume and risk retirements ; and about $ 50 million from the completion of purchased intangible asset amortization on certain f-16 contracts .partially offsetting the increases was lower operating profit of about $ 90 million from the f-35 development contract primarily due to the inception- to-date effect of reducing the profit booking rate in the second quarter of 2012 ; approximately $ 50 million from decreased production volume and risk retirements on the f-22 program partially offset by a resolution of a contractual matter in the second quarter of 2012 ; and approximately $ 45 million primarily due to a decrease in risk retirements on other sustainment activities partially offset by various other aeronautics programs due to increased risk retirements and volume .operating profit for c-5 programs was comparable to 2011 .adjustments not related to volume , including net profit booking rate adjustments and other matters described above , were approximately $ 30 million lower for 2012 compared to 2011 .2011 compared to 2010 aeronautics 2019 net sales for 2011 increased $ 1.3 billion , or 10% ( 10 % ) , compared to 2010 .the growth in net sales primarily was due to higher volume of about $ 850 million for work performed on the f-35 lrip contracts as production increased ; higher volume of about $ 745 million for c-130 programs due to an increase in deliveries ( 33 c-130j aircraft delivered in 2011 compared to 25 during 2010 ) and support activities ; about $ 425 million for f-16 support activities and an increase in aircraft deliveries ( 22 f-16 aircraft delivered in 2011 compared to 20 during 2010 ) ; and approximately $ 90 million for higher volume on c-5 programs ( two c-5m aircraft delivered in 2011 compared to one during 2010 ) .these increases partially were offset by a decline in net sales of approximately $ 675 million due to lower volume on the f-22 program and lower net sales of about $ 155 million for the f-35 development contract as development work decreased. .

Question: what was the percent of the growth in the sales from 2011 to 2012
Answer: 4.1%
