Federated Hermes Fund for U.S. Government Securities II Investment Risks - Federated Hermes Fund for U.S. Government Securities II	Feb. 28, 2025
MBS Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	MBS Risk. A rise in interest rates may cause the value of MBS held by the Fund to decline. Certain MBS issued by GSEs are not backed by the full faith and credit of the U.S. government. A non-agency MBS is subject to the risk that the value of such security will decline, because the security is not issued or guaranteed as to principal or interest by the U.S. government or a GSE. The Fund’s investments in collateralized mortgage obligations (CMOs) may entail greater market, prepayment and liquidity risks than other MBS.
Asset Backed Securities ABS Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Asset-Backed Securities (ABS) Risk. The value of asset-backed securities (ABS) may be affected by certain factors such as interest rate risk, credit risk, prepayment risk and the availability of information concerning the pool of underlying assets and its structure. Under certain market conditions, ABS may be less liquid and may be difficult to value. Movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain types of ABS. ABS can also be subject to the risk of default on the underlying assets.
Interest Rate Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. The longer the duration of a fixed-income security, the more susceptible it is to interest rate risk. Recent and potential future changes in monetary policy made by central banks and/or their governments are likely to affect the level of interest rates.
Credit Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Credit Risk. It is possible that borrowers of non-agency MBS in which the Fund invests will fail to pay interest or principal on these securities when due, which would result in the Fund losing money.
Counterparty Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Counterparty Risk. Counterparty risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose money or to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.
Prepayment and Extension Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Prepayment and Extension Risk. When homeowners prepay their mortgages in response to lower interest rates, the Fund will be required to reinvest the proceeds at the lower interest rates available. Also, when interest rates fall, the prices of mortgage-backed securities may not rise to as great an extent as those of other fixed-income securities due to the potential prepayment of higher interest mortgages. When interest rates rise, homeowners are less likely to prepay their mortgages. A decreased rate of prepayments lengthens the expected maturity of a mortgage-backed security, and the price of mortgage-backed securities may decrease more than the price of other fixed income securities when interest rates rise.
Risk of Security Downgrades [Member]
Prospectus [Line Items]
Risk [Text Block]	Risk of Security Downgrades. The downgrade of the credit of a security held by the Fund may decrease its value. Fixed-income securities with lower ratings tend to have a higher probability that a borrower will default or fail to meet its payment obligations.
Liquidity Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Liquidity Risk. The non-agency MBS and CMOs in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities.
Leverage Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Leverage Risk. Leverage risk is created when an investment exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund’s risk of loss and potential for gain.
Risk of Investing in Derivative Instruments [Member]
Prospectus [Line Items]
Risk [Text Block]	Risk of Investing in Derivative Instruments. The Fund’s exposure to derivative contracts (either directly or through its investment in another investment company) involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. The use of derivatives can lead to losses because of adverse movements in the price or value of the asset, index, rate or instrument underlying a derivative, due to failure of a counterparty, or the failure of the counterparty to meet its obligations under the contract, or due to tax or regulatory constraints. Derivatives may create investment leverage in the Fund, which magnifies the Fund’s exposure to the underlying investment. Derivative instruments may be difficult to value, may be illiquid and may be subject to wide swings in valuation caused by changes in the value of the underlying instrument. Over-the-counter derivative contracts generally carry greater liquidity risk than exchange-traded contracts. The loss on derivative transactions may substantially exceed the initial investment.
Risk Related to the Economy [Member]
Prospectus [Line Items]
Risk [Text Block]	Risk Related to the Economy. The value of the Fund’s portfolio may decline in tandem with a drop in the overall value of the markets in which the Fund invests and/or other markets. Global economic, political and financial conditions, including geopolitical and other events (e.g., wars, tensions, sanctions and terrorism) legislative changes or shifts in fiscal or monetary policy or reform, industry or economic trends and developments, grid congestion or capacity constraints, natural disasters or public health risks, such as epidemics or pandemics, may, from time to time, and for varying periods of time, have a significant effect on the economies of many nations including the U.S., and financial markets generally cause the Fund to experience volatility, illiquidity, loss of value, shareholder redemptions, and/or other potentially adverse effects. Among other investments, lower-grade bonds may be particularly sensitive to changes in the economy.
Technology Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Technology Risk. The Adviser uses various technologies in managing the Fund, consistent with its investment objective(s) and strategy described in this Prospectus. For example, proprietary and third-party data and systems are utilized to support decision-making for the Fund. Data imprecision, software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance.
Risk Lose Money [Member]
Prospectus [Line Items]
Risk [Text Block]	All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund.
Risk Not Insured Depository Institution [Member]
Prospectus [Line Items]
