Compared to [[liquid-fuel rocket|liquid propellant rocket]]s, the [[solid rocket|solid-propellant motors]] (SRMs) have been capable of providing large amounts of thrust with a relatively simple design.<ref>{{Cite web|title = What are the types of rocket propulsion?|url = http://www.qrg.northwestern.edu/projects/vss/docs/propulsion/2-what-are-the-types-of-rocket-propulsion.html|website = www.qrg.northwestern.edu|access-date = 2016-02-08}}</ref> They provide greater thrust without significant refrigeration and insulation requirements, and produce large amounts of thrust for their size. Adding detachable SRBs to a vehicle also powered by liquid-propelled rockets known as [[Staging (rocketry)|staging]] reduces the amount of liquid propellant needed and lowers the launch rig mass. Solid boosters are cheaper to design, test, and produce in the long run compared to the equivalent liquid propellant boosters.{{cn|date=December 2024}} Reusability of components across multiple flights, as in the Shuttle assembly, also has decreased hardware costs.<ref>{{Cite web|url = http://www.tsgc.utexas.edu/archive/general/ethics/boosters.html|title = Doomed from the Beginning:The Solid Rocket Boosters for the Space Shuttle|website = Texas Space Grant Consortium|publisher = University of Texas|last = Hoover|first = Kurt|access-date = 2016-02-08|archive-date = 2022-01-20|archive-url = https://web.archive.org/web/20220120020716/http://www.tsgc.utexas.edu/archive/general/ethics/boosters.html|url-status = dead}}</ref>

One example of increased performance provided by SRBs is the [[Ariane 4]] rocket. The basic 40 model with no additional boosters was capable of lifting a 4,795 lb (2,175 kg) payload to [[geostationary transfer orbit]].<ref>{{citation | publisher = Astronautix | url = http://www.astronautix.com/lvs/ariane4.htm | title = Ariane 4 | url-status = dead | archive-url = https://web.archive.org/web/20120716181149/http://www.astronautix.com/lvs/ariane4.htm | archive-date = 2012-07-16 }}.</ref> The 44P model with 4 solid boosters has a payload of 7,639 lb (3,465&nbsp;kg) to the same orbit.<ref>{{citation | publisher = Astronautix | url = http://www.astronautix.com/lvs/arine44p.htm | title = Ariane 44P | url-status = dead | archive-url = https://web.archive.org/web/20110513234146/http://www.astronautix.com/lvs/arine44p.htm | archive-date = 2011-05-13 }}.</ref>
