The CH-47D shares the same airframe as earlier models, with more powerful engines. Early CH-47Ds were powered by two T55-L-712 engines. The most common engine is the later T55-GA-714A. With its triple-hook cargo system, the CH-47D can carry heavy payloads internally and up to {{convert|26000|lb|kg|abbr=on}} (such as {{convert|40|ft|m|adj=on|disp=or|sp=us}} containers) externally. It was introduced into service in 1979. In air assault operations, it often serves as the principal mover of the 155&nbsp;mm [[M198 howitzer]], plus 30 rounds of ammunition, and an 11-man crew. The CH-47D has advanced avionics, including [[Global Positioning System]]. Nearly all US Army CH-47Ds were converted from previous A, B, and C models, a total of 472 being converted. The last U.S. Army CH-47D built was delivered to the [[U.S. Army Reserve]], located at [[Fort Hood, Texas]], in 2002.<ref>[http://www.chinook-helicopter.com/history/CH-47D_Model_History.html Boeing CH-47D model Chinook helicopters] {{Webarchive |url=https://web.archive.org/web/20080803032657/http://www.chinook-helicopter.com/history/CH-47D_Model_History.html |date=3 August 2008}}. chinook-helicopter.com</ref>

In 1993, the Netherlands signed an agreement with Canada to acquire seven CH-147Cs that were no longer in use with the [[Royal Canadian Air Force|RCAF]]. These airframes where upgraded by Boeing to CH-47D standard and delivery took place between August 1995 and February 1996. Six more new CH-47Ds were delivered by Boeing in 1998 for a total of 13,<ref>{{Cite web |title=Service history of the Boeing CH-47 Chinook with the RNLAF |url=http://www.karo-aviation.nl/photo/RNLAF/pages/CH-47%20rnlaf.htm |access-date=13 February 2025 |website=karo-aviation.nl}}</ref> of which two where lost in 2005 while on duty in Afghanistan. The Dutch CH-47Ds are improved over U.S. Army CH-47Ds, including a long nose for a Bendix weather radar, a "[[glass cockpit]]", and improved T55-L-714 engines. Between 2015 and 2023, the Netherlands replaced all 11 remaining CH-47Ds with 14 newly built CH-47Fs. The six CH-47Fs that where already in service have been upgraded to the same "MYII CAAS" standard as the newly built helicopters.<ref name="defensie2">{{Cite web |date= |title=Chinook-transporthelikopter |url=https://www.defensie.nl/onderwerpen/materieel/vliegtuigen-en-helikopters/boeing-ch-47f-chinook-transporthelikopter |access-date=13 February 2025 |website=defensie.nl}}</ref>
