Thanks, Neil. Starting with Collins Aerospace on slide four. Sales were $4.6 billion in the quarter, up 7% on an adjusted basis and up 9% on an organic basis, driven primarily by the continued recovery in the commercial aerospace end markets. By channel, commercial aftermarket sales were up 38%, driven by a 44% increase in parts and repair, a 43% increase in provisioning and a 22% increase in modifications and upgrades. Sequentially, commercial aftermarket sales were up 4%, roughly in line with our expectations. Commercial OE sales were down 3%, with strength in narrow-body more than offset by lower wide-body deliveries, primarily 787. And military sales were down 5% on an adjusted basis and down 1% organically on a tough compare. Recall, Collins' military sales were up 8% in the same period last year.
Adjusted operating profit of $480 million was up $407 million from the prior year. Higher commercial aftermarket sales, favorable mix and synergy capture more than offset lower military volume. Looking ahead, due to expected supply chain pressures and 787 OE delivery headwinds, we now expect Collins full year sales to be down mid-single digit. However, given the continued recovery in the commercial aftermarket and the benefit of cost-containment measures, we are increasing Collins full year operating profit outlook to a new range of up $250 million to $300 million versus 2020. Shifting to Pratt & Whitney on slide five. Sales of $4.7 billion were up 25% on an adjusted basis and up 35% on an organic basis, primarily driven by the continued recovery of the commercial aerospace industry.
Commercial aftermarket sales were up 56% in the quarter, with legacy large commercial engine shop visits up 49% and Pratt Canada shop visits up 18%. Sequentially, commercial aftermarket sales were up 17%. Commercial OE sales were up 22%, driven by higher GTF deliveries within Pratt's large commercial engine business. The military business sales were up 2% on another tough compare. Recall, Pratt military sales were up 11% in the same period last year. Growth in the quarter was driven by a continued ramp in F-135 sustainment, which was particularly offset -- input on production and classified development programs. Adjusted operating profit of $189 million was better than expected and was up $232 million from the prior year.
Drop-through on higher commercial aftermarket sales, more than offset the impact of higher commercial OE volume and higher SG&A and E&D. Looking ahead, due to the continued commercial aerospace recovery, we now expect Pratt's full year sales to be up mid-single digit. In addition, we are increasing Pratt's full year operating profit outlook to a new range of flat to up $50 million versus 2020. Turning now to slide six. RIS sales of $3.7 billion were in line with prior year results on an adjusted basis and down 1% on an organic basis, driven primarily by the timing of material input from suppliers. Adjusted operating profit in the quarter of $391 million was in line with expectations and was up $41 million year-over-year on an adjusted basis, driven primarily by higher program efficiencies.
RIS had $2.9 billion of bookings in the quarter, resulting in a book-to-bill of 0.84, as expected, and a backlog of $18.7 billion. Significant bookings included approximately $1 billion on classified programs. It's worth noting that we expect RIS full year book-to-bill to be greater than 1. Turning to RIS full year outlook. Due to the timing of material inputs from suppliers, we now see RIS sales growing low single digit. However, as a result of improved productivity, we continue to expect RIS' operational -- operating profit to grow $150 million to $175 million versus adjusted pro forma 2020. Turning now to slide seven. RMD sales were $3.9 billion, up 7% on an adjusted basis and up 5% on an organic basis, driven by liquidations of precontract costs on an AMRAAM award received in the quarter and the expected ramp in our NASAMS franchise.
Adjusted operating profit of $490 million was in line with our expectations and was up $59 million versus the prior year, primarily on higher sales volume. RMD's bookings in the quarter were approximately $3.9 billion, resulting in a book-to-bill of 1.02 and a backlog of $29.6 billion. Significant bookings in the quarter included AMRAAM Lot 35 for $570 million, a Patriot GEM-T order for $432 million as well as several other notable awards. We also expect RMD's full year book-to-bill to be greater than 1. We remain confident in our full year outlook for RMD, with sales growing low to mid-single digit and operating profit growing $50 million to $75 million versus adjusted pro forma 2020.
And now I'll turn it back to Neil to provide some color on the rest of the year.
