Bull left Canada and moved to [[Brussels]], where a subsidiary of SRC called [[Poudreries Réunies de Belgique|European Poudreries Réunies de Belgique]] was based. Bull continued working with the ERFB ammunition design, developing a range of munitions that could be fired from existing weapons. A number of companies designed upgrades to work with older weapons, like the [[M114 155 mm howitzer]], combining a new barrel from the M109 with Bull's ERFB ammunition to produce an improved weapon for relatively low cost.

Bull also continued working with the GC-45 design, and soon secured work with the People's Republic of [[China]],<ref>{{cite news|title=The Guns of Saddam |author=William Scott Malon|newspaper=The Washington Post|url=https://www.washingtonpost.com/archive/opinions/1991/02/10/the-guns-of-saddam/e31bbb3a-52c3-4f29-bc47-cca57a80b6db/|access-date=2018-08-29|date=February 10, 1991}}</ref> and then [[Iraq]]. He designed two artillery pieces for the Iraqis: the 155&nbsp;mm ''Al-Majnoonan'', an updated version of the G5, and a similar set of adaptations applied to the 203&nbsp;mm US [[M110 howitzer]] to produce the 210&nbsp;mm [[Al-Fao]] with a maximum range of {{convert|56|km|mi|abbr=on}} without base bleed. Although it appears the Al-Fao was not put into production, the Al-Majnoonan started replacing Soviet designs as quickly as they could be delivered. When deliveries could not be made quickly enough, additional barrels were ordered from South Africa. The guns were built and sold through an [[Austria]]n intermediary.

Based on his HARP results, Bull secured additional Iraqi funding and support for the construction of a smoothbore gun barrel assembly. He received a $25m down-payment for the project on condition that he continued the development work on the ''Al-Majnoonan'' and ''Al-Fao'' guns.<ref name="BBC Future">{{cite news|title=The tragic tale of Saddam Hussein's 'supergun'|author=William Park|publisher=BBC|url=https://www.bbc.com/future/article/20160317-the-man-who-tried-to-make-a-supergun-for-saddam-hussein|access-date=2021-02-12|date=17 March 2016}}</ref> Initially, a smaller 45-meter, 350&nbsp;mm caliber gun (known as ''Baby-Babylon''){{sfnp|Schedel|1993|p=90}} was completed for testing purposes and then Bull started work on the "real" ''PC-2'' machine, a gun that was 150 meters long, weighed 1,510 tonnes, with a bore of one meter (39&nbsp;inches) that would allow the firing of multi-stage rocket-assisted shells with a range of over {{convert|5000|mi|km|abbr=on}} or to launch {{convert|1200|lb|kg|abbr=on}} satellites into orbit.<ref name="BBC Future"/> The project objective was to eventually provide Iraq with three 350&nbsp;mm ''Baby Babylon'' guns and two 1000&nbsp;mm PC-2 ''Big Babylon'' guns.{{sfnp|Schedel|1993|p=90}}

The Iraqis then told Bull they would go ahead with the project only if he would also help with development of their longer-range [[Scud]]-based missile project. Bull agreed. Construction of the individual sections of the new gun started in England at [[Sheffield Forgemasters]] and Matrix Churchill as well as in Spain, the [[Netherlands]], and [[Switzerland]] while he concurrently worked on the [[Scud]] project,<ref name="BBC Future"/> making calculations for the new nose cone needed for the greater re-entry speeds and temperatures the missile would face.
