the year and was up 30 % over the prior year . the improvements in our revenue levels were led by renewed vigor in our federal services group markets , for which revenues increased by 83 % . strong contract funding awards in 2016 allowed us to finish the year with a contract funded backlog that positions us well as we head into 2017. increased revenues from our supply chain management group and a full year of revenue from our aviation group ( as compared to eleven months in 2015 when we acquired these businesses ) also contributed to our revenue growth in 2016. we are encouraged to see contributions to our federal services group revenue base from both our long time programs and newer programs . activity on our fms program has increased over the past year , including work to transfer two frigates to taiwan and equipment supply services to u.s. navy foreign client countries . our equipment refurbishment services for u.s. army reserve transportation equipment and other assets

foreign client countries . we are extending these relationships to market our services to several international clients . revenues for our supply chain management group have increased in 2016 at more modest levels than the previous two years . although our vehicle parts supply and inventory management support for the usps delivery vehicle fleet continue to be the primary drivers of this group 's successful results , 2016 revenue growth for this group has been provided by greater diversification and growth of parts sales to the dod , increased supply chain and inventory management support for commercial vehicle fleets , and revenue from our acquisition of ultra seating company in december 2015. we continue to broaden our base of commercial clients and make progress toward capturing new commercial vehicle fleet clients . we are a key partner with the usps and our mission critical supply chain support should continue to be essential in sustaining the aging usps fleet as this client embarks on a lengthy procurement process to acquire a new class of delivery vehicles to both augment and replace older vehicles . the usps anticipates the first deployment of a small number of newly produced vehicles will occur in three or four years . at that point in time , production and procurement of vehicles will be scheduled to occur annually over a seven-year period . usps ' previously published vehicle procurement time lines continue to experience changes and delays . based on the size , scope , and complexity of usps ' new vehicle procurement strategy , we can not be certain of the timing and quantities of new vehicles to be deployed . we also can not determine the timing or number of existing delivery vehicles that will be redeployed for other routes or purposes . while we will not participate in the competition to provide new vehicles , we will be seeking to participate with the selected providers to offer original content , program management , and warranty support . aftermarket parts supply and supply chain services to support the usps ' newly acquired vehicles will be part of our model in addition to continuing our support for older usps vehicles that remain in service . in 2016 the usps disclosed that 1.1 million addresses were added to their delivery network and shipping and packaging volume increased by half a billion items in 2015 , all contributing to an increased requirement for delivery capacity which may require a combination of both old and new vehicles for longer than currently planned . story_separator_special_tag approximately $ 900 thousand
