Too early to say. If investigations clear ST, then the investigations itself serves as due diligence to vindicate the deal as clean, making the deal more likely.
If not, then those involved at ST will probably lose their jobs, and deserved so as this will impact ST's ability to clinch future deals.
Like in any court case, ST should be presumed innocent until proven guilty. Nothing to suggest ST isn't innocent at this time.
Probably all the major or key arms suppliers in the world have been blacklisted while those that are not blacklisted probably do not wish to participate in bids anyway.
The M198 155mm towed howitzer is a medium artillery system that provides direct support fires on an interim basis to the Stryker Brigade Combat Teams and direct general support fires to light and special purpose forces (Airborne and Air Assault). As the successor to the older M114A1 155mm towed system fielded in World War II, the M198 provides significant improvements in lethality, range, reliability, availability, emplacement and movement. Normally towed by a 5-ton truck, the M198 system can also be dropped by parachute or transported by a CH47 Chinook helicopter or C130 aircraft.
The carriage of the M198 has a retractable suspension system and a top carriage which can be rotated 180 degrees to decrease overall length for shipment or storage. The fire control equipment may be used by one or two crewman for direct or indirect fire. The gunner on the left side controls left and right (traversing) settings and the assistant gunner on the right side controls up and down (elevation) settings.
Pegasus was dropped because we refuse to play their game?
If true, ACA/CID should launch a local investigation into ST to root out unsavoury practices.
