2011 compared to 2010 mfc 2019s net sales for 2011 increased $ 533 million , or 8% ( 8 % ) , compared to 2010 .
the increase was attributable to higher volume of about $ 420 million on air and missile defense programs ( primarily pac-3 and thaad ) ; and about $ 245 million from fire control systems programs primarily related to the sof clss program , which began late in the third quarter of 2010 .
partially offsetting these increases were lower net sales due to decreased volume of approximately $ 75 million primarily from various services programs and approximately $ 20 million from tactical missile programs ( primarily mlrs and jassm ) .
mfc 2019s operating profit for 2011 increased $ 96 million , or 10% ( 10 % ) , compared to 2010 .
the increase was attributable to higher operating profit of about $ 60 million for air and missile defense programs ( primarily pac-3 and thaad ) as a result of increased volume and retirement of risks ; and approximately $ 25 million for various services programs .
adjustments not related to volume , including net profit rate adjustments described above , were approximately $ 35 million higher in 2011 compared to 2010 .
backlog backlog increased in 2012 compared to 2011 mainly due to increased orders and lower sales on fire control systems programs ( primarily lantirn ae and sniper ae ) and on various services programs , partially offset by lower orders and higher sales volume on tactical missiles programs .
backlog increased in 2011 compared to 2010 primarily due to increased orders on air and missile defense programs ( primarily thaad ) .
trends we expect mfc 2019s net sales for 2013 will be comparable with 2012 .
we expect low double digit percentage growth in air and missile defense programs , offset by an expected decline in volume on logistics services programs .
operating profit and margin are expected to be comparable with 2012 results .

2012 compared to 2011 mst 2019s net sales for 2012 increased $ 447 million , or 6% ( 6 % ) , compared to 2011 .
the increase in net sales for 2012 was attributable to higher volume and risk retirements of approximately $ 395 million from ship and aviation system programs ( primarily ptds ; lcs ; vls ; and mh-60 ) ; about $ 115 million for training and logistics solutions programs primarily due to net sales from sim industries , which was acquired in the fourth quarter of 2011 ; and approximately $ 30 million as a result of increased volume on integrated warfare systems and sensors programs ( primarily aegis ) .
partially offsetting the increases were lower net sales of approximately $ 70 million from undersea systems programs due to lower volume on an international combat system program and towed array systems ; and about $ 25 million due to lower volume on various other programs .
mst 2019s operating profit for 2012 increased $ 92 million , or 14% ( 14 % ) , compared to 2011 .
the increase was attributable to higher operating profit of approximately $ 175 million from ship and aviation system programs , which reflects higher volume and risk retirements on certain programs ( primarily vls ; ptds ; mh-60 ; and lcs ) and reserves of about $ 55 million for contract cost matters on ship and aviation system programs recorded in the fourth quarter of 2011 ( including the terminated presidential helicopter program ) .
partially offsetting the increase was lower operating profit of approximately $ 40 million from undersea systems programs due to reduced profit booking rates on certain programs and lower volume on an international combat system program and towed array systems ; and about $ 40 million due to lower volume on various other programs .
adjustments not related to volume , including net profit booking rate adjustments and other matters described above , were approximately $ 150 million higher for 2012 compared to 2011. .
