Editing High-test peroxide (section)

==Applications==
When used with a suitable catalyst, HTP can be used as a [[monopropellant]],<ref>{{cite web|url=https://www.esa.int/About_Us/Business_with_ESA/Small_and_Medium_Sized_Enterprises/SME_Achievements/Green_Hydrogen_Peroxide_H2O2_monopropellant_with_advanced_catalytic_beds|title=Green Hydrogen Peroxide (H2O2) Monopropellant with Advanced Catalyst Beds|publisher=ESA|access-date=July 25, 2018}}</ref> or with a separate fuel as a [[bipropellant]].<ref>{{cite web|url=https://www.esa.int/Our_Activities/Space_Engineering_Technology/Shaping_the_Future/Development_of_a_low_thrust_bipropellant_thruster_based_on_green_propellants/(print)|title=Development of a Low Thrust Bipropellant Thruster Based on Green Propellants|publisher=ESA|access-date=July 25, 2018}}</ref>

HTP has been used safely and successfully in many applications, beginning with German usage during [[World War II]], and continues to the present day.<ref>{{cite web |url=https://www.hydrogen-peroxide.us/history-US-General-Kinetics/AIAA-1999-2739_A_Brief_History_of_Concentrated_Hydrogen_Peroxide_Uses-pitch.pdf |title=A Brief History of Concentrated Hydrogen Peroxide Uses |first1=M. |last1=Ventura |first2=G. |last2=Garboden |work=General Kinetics |date=19 June 1999 |access-date=12 November 2016 |via=Whiskey Yankee LLC}}</ref> During World War II, high-test peroxide was used as an oxidizer in some German [[bipropellant rocket]] designs, such as the [[Walter HWK 109-509|Walter HWK 509A]] rocket engine that powered the [[Messerschmitt Me 163]] point defense interceptor fighter late in World War II, comprising 80% of the standardized mixture ''[[T-Stoff]]'', and also in the [[German Type XVII submarine]].

Some significant United States programs include the reaction control thrusters on the [[X-15]] program, and the [[Bell Rocket Belt]]. The NASA [[LLRV|Lunar Lander Research Vehicle]] used it for rocket thrust to simulate a lunar lander.

The [[Royal Navy]] experimented with HTP as the oxidiser in the experimental high-speed target/training [[submarines]] {{HMS|Explorer|submarine|2}} and {{HMS|Excalibur||2}} between 1958 and 1969.

The first Russian HTP torpedo was known by the strictly functional name of [[Type 53 torpedo|53-57]], the 53 referring to the diameter in centimeters of the torpedo tube, the 57 to the year it was introduced. Driven by the [[Cold War]] competition, they ordered the development of a larger HTP torpedo, to be fired from the 65-centimeter (26-inch) tubes. HTP in one of these [[Type 65 torpedo]]es  on August 12, 2000 exploded on board and sank the [[Russian submarine Kursk (K-141)|K-141 ''Kursk'']] submarine.

British experiments with HTP as a torpedo fuel were discontinued after a peroxide fire resulted in the loss of the submarine {{HMS|Sidon|P259}} in 1956.

British experimentation with HTP continued in rocketry research, ending with the [[Black Arrow]] launch vehicles in 1971. Black Arrow rockets successfully launched the [[Prospero X-3]] satellite from [[Woomera, South Australia]] using HTP and [[kerosene]] fuel.

The British [[Blue Steel (missile)|Blue Steel missile]], attached to [[Avro Vulcan|Vulcan]] and [[Handley Page Victor|Victor]] bombers, in the 1960s, was produced by [[Avro]].  It used 85% concentration of HTP.  To light the twin chamber Stentor rocket, HTP passed through a catalyst screen.  Kerosene was then injected into the two chambers to produce {{convert|20000|and|5000|lbs|abbr=off}} of thrust each. The larger chamber was for climbing and accelerating, while the small chamber was to maintain cruise speed.  The missile had a range of 100 nautical miles when launched at high altitude and about 50 nautical miles launched at low level ({{convert|500|to|1000|feet|abbr=off}}).  Its speed was about Mach 2.0.  After a high altitude launch it would climb to {{convert|70000|to|80000|feet|abbr=off}}.  From a low level launch, it would climb to only {{convert|40000|feet|abbr=off}} but its speed would still be around Mach 2.0

With concentration of 82%, it is still in use on the Russian [[Soyuz (rocket family)|Soyuz rocket]] to drive the [[turbopump]]s on the [[booster rocket|boosters]] and on the [[orbital vehicle]].

The [[Blue Flame (automobile)|Blue Flame]] rocket-powered vehicle achieved the world land speed record of {{convert|622.407|mph}} on October 23, 1970, using a combination of high-test peroxide and [[liquified natural gas]] (LNG), pressurized by helium gas.

Propellant-grade hydrogen peroxide is being used on current military systems and is in numerous defense and aerospace research and development programs. Many privately funded rocket companies are using hydrogen peroxide, such as [[Blue Origin]] and the defunct [[Armadillo Aerospace]]; and some amateur groups have expressed interest in manufacturing their own peroxide, both for their use and for sale in small quantities to others. HTP is used on [[ILR-33 AMBER]]<ref>{{Cite web|last=Cieśliński|first=Dawid|date=2021|title=Polish civil rockets' development overview|url=https://www.researchgate.net/publication/355481109}}</ref> and Nucleus<ref>{{Cite web|title=Nucleus: A Very Different Way to Launch into Space|url=https://www.nammo.com/story/a-very-different-way-to-launch-into-space/|access-date=2022-02-06|website=Nammo|language=en-US}}</ref> [[suborbital rocket]]s.

HTP was planned for use in an attempt to break the land speed record with the [[Bloodhound SSC]] car, aiming to reach over {{convert|1000|mph}}. HTP would have been the oxidiser for the hybrid fuel rocket, reacting with the solid fuel [[hydroxyl-terminated polybutadiene]]. The project stalled due to the Covid-19 pandemic and lack of funding.
