The Apollo 7 spacecraft included Command and Service Module 101 (CSM-101), the first Block{{spaces}}II CSM to be flown. The Block{{spaces}}II craft had the capability of docking with a LM,{{sfn|Orloff & Harland 2006|p=172}} though none was flown on Apollo{{spaces}}7. The spacecraft also included the [[launch escape system]] and a spacecraft-lunar module adapter (SLA, numbered as SLA-5), though the latter included no LM and instead provided a mating structure between the SM and the [[S-IVB]]'s Instrument Unit,{{sfn|Press Kit|pp=25–26}}<ref name = "hardware">{{cite web|title=Apollo/Skylab ASTP and Shuttle Orbiter Major End Items|date=March 1978|url=https://s3.documentcloud.org/documents/6473665/Apollo-Skylab-ASTP-and-Shuttle-Orbiter-Major-End.pdf |archive-url=https://ghostarchive.org/archive/20221009/https://s3.documentcloud.org/documents/6473665/Apollo-Skylab-ASTP-and-Shuttle-Orbiter-Major-End.pdf |archive-date=2022-10-09 |url-status=live|publisher=[[NASA]]|page=5}}</ref> with a structural stiffener substituted for the LM.{{sfn|Mission Report|p=A-43}} The launch escape system was jettisoned after S-IVB ignition,{{sfn|Mission Report|p=A-41}} while the SLA was left behind on the spent S-IVB when the CSM separated from it in orbit.{{sfn|Mission Report|p=A-43}}

Following the Apollo 1 fire, the Block{{spaces}}II CSM was extensively redesigned—more than 1,800 changes were recommended, of which 1,300 were implemented for Apollo{{spaces}}7.<ref name = "launch" /> Prominent among these was the new aluminum and [[fiberglass]] outward-opening hatch, which the crew could open in seven seconds from within, and the pad crew in ten seconds from outside. Other changes included replacement of aluminum tubing in the high-pressure oxygen system with stainless steel, replacement of flammable materials with non-flammable (including changing plastic switches for metal ones) and, for crew protection in the event of a fire, an emergency oxygen system to shield them from toxic fumes, as well as firefighting equipment.{{sfn|Press Kit|p=29}}

After the [[Gemini 3]] craft was dubbed ''[[Molly Brown]]'' by Grissom, NASA forbade naming spacecraft.{{sfn|Shepard, Slayton, & Barbree 1994|pp=227–228}} Despite this prohibition, Schirra wanted to name his ship "Phoenix," but NASA refused him permission.{{sfn|Orloff & Harland 2006|p=172}} The first CM to be given a call sign other than the mission designation would be that of [[Apollo 9]], which carried a LM that would separate from it and then re-dock, necessitating distinct call signs for the two vehicles.{{sfn|French & Burgess 2007|p=340}}
