SMArt 155 is a German DM702 155 mm artillery projectile that releases two autonomous sensor-fuzed submunitions over an armored target area. Diehl identifies GIWS as the Diehl-Rheinmetall joint venture behind the munition, Rheinmetall describes the round as a fire-and-forget top-attack projectile for 155 mm guns, and SIPRI records a 2022 German transfer of DM702 SMART-155 guided shells to Ukraine.
SIPRI records 100 second-hand DM-702 SMART-155 guided shells transferred from Germany to Ukraine in 2022 as aid after Russia's full-scale invasion; Germany's delivery list separately names delivered 155 mm precision ammunition including SMArt, and Militarnyi identifies a DM702 projectile frame from a Ukrainian 43rd Artillery Brigade video.
Role detailsSMArt 155 packages two autonomous attack modules inside a 155 mm carrier shell. After the carrier ejects them above the target area, each submunition descends under a ballute/parachute arrangement, searches with onboard sensors, and fires an explosively formed penetrator downward when it detects a suitable armored target.
GD-OTS/GIWS material describes a thin-walled shell body, base plate, ejection unit, time fuze, and two functionally identical submunitions.
Rheinmetall describes autonomous submunitions with multi-mode sensors; specialist coverage identifies infrared and millimeter-wave sensing.
The Ukraine evidence trail includes official transfer listing and identified DM702 imagery, but many strike videos are too compressed or distant to separate SMArt from other top-attack 155 mm rounds.

Public sources use SMArt 155, SMArt155, DM702, and DM702A1 for the same German 155 mm sensor-fuzed projectile family; the DM702 naming is the Bundeswehr ammunition designation.
SMArt 155 is a munition rather than a gun system. The linked firing weapons below are limited to cataloged systems where the cited sources identify the connection.

The German government's Bundestag response confirmed DM702A1 obsolescence work through 2027 and planned procurement of roughly 10,000 additional SMArt 155 rounds from 2027.
