Großwald Systems: D-LBO — Digitalisierung Landbasierter Operationen

Programme genealogy

The radio core predates the programme. Rohde & Schwarz was appointed SVFuA (Streitkräftegemeinsame Verbundfähige Funkgeräteausstattung) project lead in 2009, anchoring software-defined radio and cryptology as a national key technology. The first procurement contract followed on 29 June 2017 — roughly €91.5 m for 50 command-vehicle sets (Puma, Boxer) with an option for 475 more. SVFuA was productised as SOVERON D; the SOVERON family is the equipment base of D-LBO.

Contract architecture

D-LBO is not a single-supplier programme. The radio layer, the vehicle integration, the IT-system integration and the dismounted interoperability fit are held by four separate industrial structures, with external consultancies engaged on programme support — a division of responsibility that matters for reading where the documented failures sit.

The Rohde & Schwarz radio award was structured as a direct award without a Europe-wide tender. Thales challenged; the OLG Düsseldorf rejected the challenge on 1 December 2023, accepting heightened security interest after the Russian invasion of Ukraine as justification. The award stood — and with it the absence of the competitive pressure a tender would have applied to the radio layer in which the 2025 test failures were later documented.

The radio layer — SOVERON

The European interoperability layer runs through ESSOR. On 22 April 2026 the Bundestag's budget committee cleared roughly €92 m for continued development of the ESSOR Narrowband Waveform, with Rohde & Schwarz as the German member of the a4ESSOR joint venture — cleared in the same Bundestag window as the wider €90 bn procurement slate tracked in Signal No. 44. NATO has adopted the ESSOR High Data Rate Waveform as an interoperability standard; D-LBO radios carrying ESSOR waveforms are Germany's path to alliance-level digital interoperability of land formations.

Test record, 2025–2026

The first full system test at Munster in May 2025 was aborted: the software-defined operation proved too complex for soldiers to set up radio nets, and the devices were assessed as not suitable for troop use. A second test in November 2025 was likewise aborted, with failures severe enough that the internal assessment classified the system as posing danger to life and limb even in training and exercise operation.

The confidential BMVg report to the Bundestag — requested by parliamentarians for weeks, described by the ministry to the defence committee as ‘too technical and barely comprehensible’, then obtained and published by Welt in April 2026 — recorded the documented state: voice transmissions between retrofitted Leopard 2 A7V tanks partially not transmitted or inaudible; no reliable confirmation to the operator that a message had gone out, making an immediate fire-stop command impossible to guarantee; Friendly Force Tracking displaying false or no position data; ranges substantially short of requirements. The formal technical rating was failing. Spending to that point: €1.749 bn on the programme plus €299 m in supporting measures. The full report-level detail is covered in the Großwald dispatch on the leaked assessment and was tracked as it broke in Signal No. 32.

The political record runs parallel. Pistorius told the Bundestag on 10 September 2025 that the programme was on schedule — four months after the first aborted test — and conceded by December that it was visibly stuck at many points. The BMVg's structural response came in late 2025: a coordination office under the Generalinspekteur and State Secretary Plötner, a dedicated programme coordinator stationed at Munster, and tightened controls at BAAINBw.

Interim architecture

Until D-LBO reaches the fleet, German land forces run a four-part stopgap. The majority of vehicles still operate the SEM 80/90 — an analogue VHF radio introduced in 1984, incompatible with NATO digital standards, encrypted only via external add-ons. The 2021 framework procured up to 30,000 rebuilt units from Thales at ~€20,000 each, deliberately specified to perform no better than the originals so that no new procurement procedure would be triggered. Panzerbrigade 45 in Lithuania runs interim digital Thales PR4G (TRC 9215-HD, TRC 9315-HD) and SYNAPS-H handheld sets, operationally tested in 2024 and cleared for NATO multinational use. The L3Harris manpacks cover dismounted and joint interoperability. And since May 2026 the BMVg has formalised mixed analogue–digital operation (Mischbetrieb), using SOVERON handhelds to network platforms that have not yet received the vehicle fit, providing encrypted digital voice and data without the integration effort that has proven the programme's bottleneck.

Recovery trajectory

As of May 2026 the indicators have turned for the first time since the programme entered crisis. A Munster retest met most Army requirements: the digital situational picture displayed reliably and voice connections were rated stable. More than 700 platforms carry the D-LBO basic fit. Retrofit sites have expanded from two to seven, with planning toward 30 assembly lines and a capacity of roughly 100 vehicles per month. Serial retrofit is indicated for summer 2026 — six months behind the January 2026 start that internal documents had flagged as questionable in mid-2025. A modification contract of roughly €2.4 bn — new-vehicle equipment plus additional digital handhelds for the mixed-operation fleet — is expected before parliament in June 2026, with reporting indicating the parliamentary commitment is not yet assured.

The Division 2025 target stands: the 10th Panzer Division digitally equipped to D-LBO basic standard and NATO-ready by early 2027, full divisional rollout by end-2027, full fleet by end-2030. Industry maintains the end-2027 commitment. One passed retest is the evidence base for all of it.

European peer comparison

Tactical-communications digitalisation is failing in structurally similar ways across Europe; the comparison frames how unusual — and how recoverable — the German position is.

The structural contrast is delivery model, not technology. France and the United States field incrementally — radios, software and platforms in synchronised slices, each fielded slice generating the test evidence for the next. D-LBO was architected as a big-bang fleet conversion whose first full-system evidence arrived at Munster in May 2025, six years and well over a billion euros into implementation. The 2026 mixed-operation pivot is, in substance, a late conversion to the incremental model — handhelds first, vehicle integration as capacity allows. The companion soldier-system track runs through IdZ-ES, whose €1.04 bn Rheinmetall order carries the dismounted side of the same digitisation architecture.

Outlook

Four variables determine whether the recovery holds. First, the June 2026 parliamentary decision on the ~€2.4 bn modification contract — the first funding vote taken with the full failure record on the table. Second, whether serial retrofit actually starts in summer 2026 and the seven sites scale toward the 100-vehicles-per-month target. Third, whether the range and Friendly Force Tracking deficiencies documented in the April report are verified as fixed in a repeatable test, not a single retest. Fourth, the end-2027 Division 2025 deadline — the date on which Germany's NATO force commitments and the programme's credibility converge, during the window in which alliance planning assumes the Russian conventional threat peaks.
