The Greek military has consistently enjoyed strong fiscal support from the central budget much to the envy of its NATO peers and the consternation of Athens’ creditors. Since the end of the Cold War, military expenditure has never dipped below 2.3% of GDP; in the 1990s it hovered between 3% and 4%. One of the major acquisition projects funded in the last two decades was a recapitalization of the Hellenic Navy’s submarine force, which operated eight German-built U-209 variants at the time the program was launched. Returning to the German shipyards, the Greek government signed a deal in 2000 with Howaldtswerke-Deutsche Werft (HDW) and Ferrostaal for three new U-214 submarines and later exercised an option to purchase another. The EUR 1.26 billion contract, however, was later found to have been made possible by EUR 100 million in bribes paid out to Greek defence officials and various consultants. A third firm, STN Atlas, paid up to EUR 13 million in bribes to ensure its sensor systems were installed onboard the new submarines.

  • Jan 1996

    The Greek navy's search for new submarines came partially in response to the war-scare, when Greece nearly came to blows with Turkey over the islet of Imia/Kardak.

  • 1996

    Later that year, Greece announced a USD 17 billion, 10-year acquisition plan.

  • 1998

    The decision to select the German acquisition option was made. The prior submarine tender was met with bids from French, Swedish, and German firms. The perceived imperative to upgrade the Greek navy was paired with a concern to preserve the country’s faltering shipbuilding sector. Thus, the contract for new Type-214 submarines was married with a takeover of Hellenic Shipyards, a fiscally distraught concern, by the HDW-Ferrostaal consortium. The negotiators agreed to offsets as well, including provisions requiring HDW to help sell Greek products abroad, to transfer know-how to Greek shipyards, and to construct everything from rail cars to new ferries.

  • 2004

    After the first submarine was completed by HDW in Kiel, the Hellenic Navy refused to accept the vessel because of a long list of alleged defects. The Germans responded, arguing that the Greeks were attempting to stall payments.

  • 2009

    The Greek government had spent EUR 2 billion on the program, with another EUR 500 million in arrears.

  • Sep 2010

    The two sides agreed to a revised deal that expanded the program to acquisition of six new submarines; in the interim, three new vessels had been laid down at Hellenic Shipyards' Skaramanga facility.

  • 2011

    The new agreement had barely been inked when investigations into the deal became public.

  • May 2011

    That year, HDW announced that it would abandon the deal amendment.

  • 2016

    The last of the four submarines ordered in 2000 and 2002 was finally delivered.

Investigation Outcomes

  • May 2010

    An investigation in Germany into bribe-giving at Ferrostaal began in May 2010, and eventually was refocused on corruption associated not only with the Greek submarine deal, but also the sale of submarines to Portugal and a compressor station to Turkmenistan.

  • May 2011

    Greek investigators with the Financial Crimes Squad (SDOE) went public with their findings and initially suggested that 37 people had been contacted by a prosecutor about their role in the submarine deal and that EUR 100 million in bribes had been distributed. The investigation also claimed that the price of the submarines was inflated through requests for extra equipment, and that this inflation allowed for more bribes to be paid. The total estimate of bribes paid was later increased to EUR 120 million.

  • Dec 2011

    As a result of the German investigation, two senior Ferrostaal employees, Johann-Friedrich Haun and Hans-Dieter Mühlenbeck, were fined and received suspended jail sentences and the company itself was fined EUR 40 million. A parallel investigation into HDW was reportedly dropped due to lack of cooperativeness from Greek authorities.

  • Oct 2013

    The parallel Greek investigation netted its most prominent conviction when former defence minister Akis Tsochatzopoulos was found guilty of laundering the bribes he received in connection with the submarine deal as well as a separate purchase of Russian missiles. Family members and associates of Tsochatzopoulos were also convicted in the trial.

  • 2013

    Antonis Kantas, the deputy head of procurement at the Defence Ministry at the time of the submarine deal, began cooperating with prosecutors in Greece.

  • Jan 2014

    A Greek agent who had worked for STN Atlas, a German electronics company controlled by BAE Systems and Rheinmetall at the time the submarine deals were signed, implicated the firm in the corruption scandal as well. According to the agent, Panagiotis Efstathiou, STN Atlas paid up to EUR 3 million in bribes to ensure its ISUS 90 sensor suite was installed on the Greek submarines.

  • Mar 2015

    In Greece, Antonis Kantas eventually provided information that led to the indictment of 32 individuals associated with the deal. Kantas' testimony hinted at the purposes of the bribery - to overcome the opposition of officials who felt that the spending spree Greece pursued after the 1996 crisis was either ill-advised overall or poorly executed in selecting equipment appropriate to the Greek military's needs.

  • Jun 2017

    After an investigation, the Bremen Public Prosecutor's Office announced in June 2017 that it had established that Atlas Elektronik GmbH, the Bremen-based successor to STN Atlas' naval systems division after a split in 2003, had paid as much as EUR 13 million in commissions related to the deal. Atlas Elektronik, which is now jointly owned by Airbus and ThyssenKrupp Marine Systems, agreed to disgorge EUR 48 million in profits stemming from the Greek deal and a separate investigation involving the sale of torpedoes to Peru. The Bremen Public Prosecutor's Office noted that investigations into the personal liability of 17 individuals would continue despite the settlement.

  • Jan 2019

    A court convicted Sotiris Emmanouil, the banker Jean-Claude Oswald, Kantas, and other defendants for taking and handling bribes in the submarine deals. Most of the defendants were handed down lengthy suspended sentences, including a 20-year sentence for Emmanouil. Oswald, who did not appear in Greece for the trial, was sentenced to five years in prison. Ministry official Spyros Travlos and several other co-defendants were found to be innocent.

  • Jan 2019

    A Greek court sentenced Efstathiou to a nine-year suspended prison term.
