What the notice says

The United States Naval Sea Systems Command (NAVSEA) intends to modify contract N0002426C4434, awarded to Walashek Industrial & Marine, Inc. (Walashek), to incorporate planning, preparation and execution of steam boiler maintenance, alteration, and repairs completed during continuous and emergent maintenance availabilities on the USS WASP (LHD 1), USS ESSEX (LHD 2), USS KEARSARGE (LHD 3), an USS BATAAN (LHD 5) in the three (3) year period of performance through 17 February 2029. The proposed action is limited to the modification of contract N0002426C4434 to incorporate the inter-availability s… (show all)

upport, inspections & assessments, engineering & design support (i.e., conducting periodic material condition inspections and assessments of the boilers and ensuring the Navy�s boiler repair specifications reflect the material condition of the ship), execution planning & preparation (i.e., preparing to complete both emergent and continuous maintenance availabilities), material procurement, maintenance, alteration and repair of the boiler systems on the USS WASP (LHD 1), USS ESSEX (LHD 2), USS KEARSARGE (LHD 3), and USS BATAAN (LHD 5) in continuous and emergent maintenance availabilities during the three (3) year period of performance through 17 February 2029. The scope includes all labor, supervision, equipment, facilities, materials and travel necessary to prepare for and accomplish these efforts. This action aligns with the contract�s current contract line item number (CLIN) structure, which includes continuous and emergent repair for USS BOXER (LHD 4) and USS IWO JIMA (LHD 7). For clarity, this scope also applies to the USS BOXER (LHD 4) and USS IWO JIMA (LHD 7). This modification adds similar continuous and emergent repair CLINs for the aforementioned four additional LHDs, as well as new CLINs for Provision Items Ordered (PIO) and travel reimbursement for each additional ship.

Value counts single-winner awards. "Shared" awards are multiple-award contracts that list every winner with the same total ceiling; that ceiling is not one company's win, so it is not added in. Revenue next to a ticker is the company's last annual revenue from its 10-K.

Investor context
  • $GD reported $42.3B revenue in FY2025. The median single-winner award in these 52 past awards, $762.4M, is 2% of that. 10-K
  • $HII reported $11.5B revenue in FY2025. The median single-winner award in these 52 past awards, $762.4M, is 7% of that. 10-K

One award's total value against one year of revenue; many awards are paid over several years.

Latest awards

Materiality: one award's value as a share of the winner's revenue over the latest 12 months in its SEC filings (or its last fiscal year, as noted when you point at it). Low under 1%, Medium 1 to 5%, High 5% or more. Many awards are paid over several years, so this overstates a single year's share.
