The Ju 87 B series was to be the first mass-produced variant. A total of six pre-production Ju 87 B-0 were produced, built from Ju 87 A airframes.<ref name="Griehl 2001, p. 63">{{harvnb|Griehl|2001|p=63}}</ref> The first production version was the Ju 87 B-1, with a considerably larger engine, its Jumo 211D generating 1,200&nbsp;PS ({{convert|883|kW|hp|abbr=on|disp=or}}), and completely redesigned fuselage and landing gear, replacing the twin radio masts of the "A" version with a single mast mounted further forward on the "greenhouse" canopy, and much simpler, lighter-weight wheel "spats" used from the -B version onwards, discarding the transverse strut bracing of the "A" version's maingear design. This new design was again tested in Spain, and after proving its abilities there, production was ramped up to 60 per month. As a result, by the outbreak of [[World War II]], the Luftwaffe had 336 Ju 87 B-1s on hand.<ref name="Griehl 2001, p. 61"/>

The B-1 was also fitted with "Lärmgeräte", essentially [[Siren (alarm)|sirens]] driven by propellers with a diameter of {{convert|0.7|m|ft|abbr=on}}<ref name="Griehl 2001, p. 64">{{harvnb|Griehl|2001|p=64}}</ref> The devices caused a loss of 20–25&nbsp;km/h (12–15&nbsp;mph) through drag, and over time the sirens were no longer installed on many units, although they remained in use to various extent. As an alternative, some bombs were fitted with whistles on the fin to produce the noise after release.<ref>{{harvnb|Griehl|2001|pp=64–65}}</ref> The trumpets were a suggestion from Udet, but some authors say the idea originated from [[Adolf Hitler]].<ref name="Boyne 1994, p. 30">{{harvnb|Boyne|1994|p=30}}</ref>

The Ju 87 B-2s that followed had some improvements and were built in several variants that included ski-equipped versions (the B-1 also had this modification)<ref>{{harvnb|Griehl|2001|p=65}}</ref> and at the other end, with a tropical operation kit called the Ju 87 B-2 trop. Italy's [[Regia Aeronautica]] received B-2s and named them the "Picchiatello", while others went to the other members of the [[Axis powers of World War II|Axis]], including Hungary, Bulgaria and Romania. The B-2 also had an oil hydraulic system for closing the [[Aircraft engine controls|cowling flaps]]. This continued in all the later designs.<ref name="Griehl 2001, p. 66">{{harvnb|Griehl|2001|p=66}}</ref>

Production of the Ju 87 B started in 1937. 89 B-1s were to be built at Junkers' factory in Dessau and another 40 at the Weserflug plant in Lemwerder by July 1937. Production would be carried out by the Weserflug company after April 1938, but Junkers continued producing Ju 87 up until March 1940.<ref name="Griehl 2001, p. 68"/>
