aeronautics 2019 operating profit for 2011 increased $132 million, or 9% (9%), compared to 2010. the increase primarily was attributable to approximately $115 million of higher operating profit on c-130 programs due to increased volume and the retirement of risks; increased volume and risk retirements on f-16 programs of about $50 million and c-5 programs of approximately $20 million; and about $70 million due to risk retirements on other aeronautics sustainment activities in 2011. these increases partially were offset by a decline in operating profit of approximately $75 million on the f-22 program and f-35 development contract primarily due to lower volume and about $55 million on other programs, including f-35 lrip, primarily due to lower profit rate adjustments in 2011 compared to 2010. adjustments not related to volume, including net profit rate adjustments described above, were approximately $90 million higher in 2011 compared to 2010. backlog backlog decreased in 2012 compared to 2011 mainly due to lower orders on f-35 contracts and c-130 programs, partially offset by higher orders on f-16 programs. backlog increased in 2011 compared to 2010 mainly due to higher orders on f-35 contracts, which partially were offset by higher sales volume on the c-130 programs. trends we expect aeronautics will experience a mid single digit percentage range decline in net sales for 2013 as compared to 2012. a decrease in net sales from a decline in f-16 and c-130j aircraft deliveries is expected to be partially offset by an increase in net sales volume on f-35 lrip contracts. operating profit is projected to decrease at a high single digit percentage range from 2012 levels due to the expected decline in net sales as well as changes in aircraft mix, resulting in a slight decline in operating margins between the years. information systems & global solutions our is&gs business segment provides management services, integrated information technology solutions, and advanced technology systems and expertise across a broad spectrum of applications for civil, defense, intelligence, and other government customers. is&gs has a portfolio of many smaller contracts as compared to our other business segments. is&gs has been impacted by the continuing downturn in the federal information technology budgets and the impact of the continuing resolution that was effective on october 1, 2012, the start of the u.s. government 2019s fiscal year. is&gs 2019 operating results included the following (in millions):.
|  | 2012 | 2011 | 2010 |
| --------- | --------- | --------- | --------- |
| Net sales | $8,846 | $9,381 | $9,921 |
| Operating profit | 808 | 874 | 814 |
| Operating margins | 9.1% | 9.3% | 8.2% |
| Backlog at year-end | 8,700 | 9,300 | 9,700 |
2012 compared to 2011 is&gs 2019 net sales for 2012 decreased $535 million, or 6% (6%), compared to 2011. the decrease was attributable to lower net sales of approximately $485 million due to the substantial completion of various programs during 2011 (primarily jtrs; odin; and u.k. census); and about $255 million due to lower volume on numerous other programs (primarily hanford; warfighter information network-tactical (win-t); command, control, battle management and communications (c2bmc); and transportation worker identification credential (twic)). partially offsetting the decreases were higher net sales of approximately $140 million from qtc, which was acquired early in the fourth quarter of 2011; and about $65 million from increased activity on numerous other programs, primarily federal cyber security programs and persistent threat detection system (ptds) operational support. is&gs 2019 operating profit for 2012 decreased $66 million, or 8% (8%), compared to 2011. the decrease was attributable to lower operating profit of approximately $50 million due to the favorable impact of the odin contract completion in 2011; about $25 million due to an increase in reserves for performance issues related to an international airborne surveillance system in 2012; and approximately $20 million due to lower volume on certain programs (primarily c2bmc and win-t). partially offsetting the decreases was an increase in operating profit due to higher risk retirements of approximately $15 million from the twic program; and about $10 million due to increased activity on numerous other programs, primarily federal cyber security programs and ptds operational support. operating profit for the jtrs program was comparable as a decrease in volume was offset by a decrease in reserves. adjustments not related to volume, including net profit booking rate adjustments and other matters described above, were approximately $20 million higher for 2012 compared to 2011. .
